Abstract
The present study describes a method for the preparation of green titanium dioxide (TiO2) nanoparticles from the peel of Solanum tuberosum, commonly known as potato, and the potato peel being a kitchen waste. The green synthesized TiO2 (G- TiO2) nanoparticles were characterized using UV-visible spectroscopy, dynamic light scattering, scanning electron microscopy, TEM, XRD, and FTIR spectroscopy. The photocatalytic activity of the G- TiO2 nanoparticles was also shown using the dye bromophenol blue. To explore the biocompatibility of the G- TiO2, the cell viability in normal as well as cancer cells was assessed. Further, the in vivo toxicity of the G- TiO2 nanoparticles was assessed using zebrafish embryos. The novelty of the present invention is to utilize kitchen waste for a useful purpose for the synthesis of titanium dioxide nanoparticles which is known to have UV light scavenging properties. Moreover, the potato peel is a natural antioxidant and possesses a skin-lightening effect. A combination of the potato peel extract and titanium dioxide prepared using the extract will have a combinatorial effect for protecting UV light exposure to the skin and lightening the skin colour.

Abstract
BACKGROUND Alzheimer's disease (AD) is diagnosed with the deposition of insoluble β-amyloid (Aβ) peptides in the neuropil of the brain leading to dementia. The extracellular deposition of the fibrillar Aβ peptide on the neurons is known as senile plaques. Therefore, Aβ degradation and clearance from the human body is a promising therapeutic approach in the medication of AD. METHODS In the current study, the enzyme lumbrokinase (LK) was extracted and purified from earthworm and its activity was utilized toward Aβ 1-42 amyloids degradation in vitro alongside with an additional enzyme serratiopeptidase (SP) considering nattokinase (NK) as a standard. RESULTS The output of this study revealed that preformed Aβ 1-42 amyloids was disintegrated by both LK and SP, as demonstrated from fluorescence assay using Thioflavin T dye. In addition, dynamic light scattering study revealed the lower size of the preformed fibrils Aβ 1-42 at various time intervals after incubation with the enzymes LK and SP. Furthermore, in silico approach showed high affinity thermodynamically favorable interaction of LK as well as SP toward Aβ 1-42 amyloid. Finally, the toxicity of degraded preformed Aβ 1-42 amyloid was assessed by MTT assay which showed reduced toxicity of enzyme treated Aβ 1-42 amyloid compared to only Aβ 1-42 amyloid. CONCLUSION The findings of the present study indicated that LK and SP, not only had Aβ 1-42 amyloid degrading potential, but also could reduce the toxicity which can make them a suitable drug candidate for AD. Furthermore, the in vivo studies are needed to be executed in future.

Abstract
Leukemia is a cancer of blood cells that mainly affects the white blood cells. In acute myeloid leukemia (AML) sudden growth of cancerous cells occurs in blood and bone marrow, and it disrupts normal blood cell production. Most patients are asymptomatic, but it spreads rapidly and can become fatal if left untreated. AML is the prevalent form of leukemia in children. Risk factors of AML include chemical exposure, radiation, genetics, etc. Conventional diagnostic methods of AML are complete blood count tests and bone marrow aspiration, while conventional treatment methods involve chemotherapy, radiation therapy, and bone marrow transplant. There is a risk of cancer cells spreading progressively to the other organs if left untreated, and hence, early diagnosis is required. The conventional diagnostic methods are time- consuming and have drawbacks like harmful side effects and recurrence of the disease. To overcome these difficulties, nanoparticles are employed in treating and diagnosing AML. These nanoparticles can be surface- modified and can be used against cancer cells. Due to their enhanced permeability effect and high surface-to-volume ratio they will be able to reach the tumour site which cannot be reached by traditional drugs. This review article talks about how nanotechnology is more advantageous over the traditional methods in the treatment and diagnosis of AML.

Abstract
Various nanomaterials have been studied for their biomedical application in recent years. Among them, nanocomposites have a prominent medical application in the prevention, diagnosis, and treatment of various diseases. Nanocomposites are made up of polymeric matrix layers composed of synthetic or natural polymers like chitosan, polyethylene glycol, etc. Polymer nanocomposites are inorganic nanoparticles dispersed in a polymer matrix. There are two types of polymeric nanocomposites which include natural and synthetic polymer nanocomposites. These nanocomposites have various biomedical applications, such as medical implants, wound healing, wound dressing, bone repair and replacement, and dental filling. Polymeric nanocomposites have a wide range of biomedical applications due to their high stability, non-immunogenic nature, sustained drug delivery, non-toxic, and can escape reticuloendothelial system uptake along with drug bioavailability improvement. In this review, we have discussed various types of natural and synthetic polymer nanocomposites and their biomedical applications.

Abstract
One of the primary threats in tumor treatment revolves around the limited ability to penetrate tumor sites, leading to reduced therapeutic effectiveness, which remains a critical concern. Recently gaining importance are novel peptides, namely CRGDK/RGPD/EC (iRGD), that possess enhanced tumor-penetrating and inhibitory properties. These peptides specifically target and penetrate tumors by binding to αvβ integrins, namely αvβ3 and αvβ5, as well as NRP-1 receptors. Remarkably abundant on both the vasculature and tumor cell surfaces, these peptides show promising potential for improving tumor treatment outcomes. As a result, iRGD penetrated deep into the tumor tissues with biological products, contrast agents (imaging agents), antitumor drugs, and immune modulators after co-injecting them with peptides or chemically linked to peptides. The synthesis of iRGD peptides is a relatively straightforward process compared to the synthesis of other traditional peptides, and they significantly improved tumor tissue penetration inhibiting tumor metastasis effectively. Recent studies demonstrate the effectiveness of iRGD-driven dual-targeting chemotherapeutics on cancer cells, and the nanocarriers were modified with iRGD, serving as a favorable delivery strategy of payloads for deeper tumor regions. This review aims to provide an overview to emphasize the recent advancements and advantages of iRGD in treating and imaging various cancers.

Abstract
It is evident that site-specific systemic drug delivery can reduce side effects, systemic toxicity, and minimal dosage requirements predominantly by delivering drugs to particular pathological sites, cells, and even subcellular structures. The endoplasmic reticulum (ER) and associated cell organelles play a vital role in several essential cellular functions and activities, such as the synthesis of lipids, steroids, membrane-associated proteins along with intracellular transport, signaling of Ca2+, and specific response to stress. Therefore, the dysfunction of ER is correlated with numerous diseases where cancer, neurodegenerative disorders, diabetes mellitus, hepatic disorder, etc., are very common. To achieve satisfactory therapeutic results in certain diseases, it is essential to engineer delivery systems that can effectively enter the cells and target ER. Nanoparticles are highly biocompatible, contain a variety of cargos or payloads, and can be modified in a pliable manner to achieve therapeutic effectiveness at the subcellular level when delivered to specific organelles. Passive targeting drug delivery vehicles, or active targeting drug delivery systems, reduce the nonselective accumulation of drugs while reducing side effects by modifying them with small molecular compounds, antibodies, polypeptides, or isolated bio-membranes. The targeting of ER and closely associated organelles in cells using nanoparticles, however, is still unsymmetrically understood. Therefore, here we summarized the pathophysiological prospect of ER stress, involvement of ER and mitochondrial response, disease related to ER dysfunctions, essential therapeutics, and nanoenabled modulation of their delivery to optimize therapy.

Abstract
Ovarian cancer cells usually spread in the peritoneal region, and if chemotherapeutic drugs can be given in these regions with proximity, then the anticancer property of the chemotherapeutic drugs can enhance. However, chemotherapeutic drug administrations are hindered by local toxicity. In the drug delivery system, microparticles or nanoparticles are administered in a controlled manner. Microparticles stay in a close vicinity while nanoparticles are smaller and can move evenly in the peritoneum. Intravenous administration of the drug evenly distributes the medicine in the target places and if the composition of the drug has nanoparticles it will have more specificity and will have easy access to the cancer cells and tumors. Among the different types of nanoparticles, polymeric nanoparticles were proven as most efficient in drug delivery. Polymeric nanoparticles are seen to be combined with many other molecules like metals, non-metals, lipids, and proteins, which helps in the increase of cellular uptake. The efficiency of different types of polymeric nanoparticles used in delivering the load for management of ovarian cancer will be discussed in this mini-review.

Abstract
Conventional chemotherapeutic drugs are used for cancer management, but recently nanoparticles have also been shown to contribute towards controlling cancer cell proliferation. In the present study, we focussed on analyzing the combinatorial effect of Cerium oxide (CeO2) nanoparticles and Doxorubicin (Dox) on melanoma cancer cells in vitro and in vivo. We entrapped CeO2, Dox, and CeO2+Dox in a hybrid polymer matrix of alginate and chitosan (Alg-Cs) and used them in both in vitro and in vivo studies to compare their anticancer effect. Scratch assay using A549 lung cancer cells showed delayed wound healing when exposed to a low and high dose of CeO2 +Dox, compared to individual components. In order to determine a safe dose of the nanoformulations, zebrafish embryos were used. Further, in vivo, testing was done on Swiss albino female mice where the melanoma was induced by applying Benzopyrene followed by UV irradiation. The animals were treated with CeO2, Dox, and CeO2+ Dox that were entrapped in Alg-Cs for further 21 days. From both in vivo and in vitro results, we concluded that CeO2 and Dox in combination had superior therapeutic efficiency in cancer cells and animals than the nude drugs.

Abstract
Photodynamic therapy (PDT) has recently become significant as a clinical modality for cancer therapy and multidrug-resistant (MDR) infections, replacing conventional chemotherapy and radiation therapy protocols. PDT involves the excitation of certain nontoxic molecules called photosensitizers (PS), applying a specific wavelength of light to generate reactive oxygen species (ROS) to treat cancer cells and other pathogens. Rhodamine 6G (R6G) is a well-known laser dye with poor aqueous solubility, and lower sensitivity poses an issue in using PS for PDT. Nanocarrier systems are needed to deliver R6G to cancer targets since PDT requires a higher accumulation of PS. It was found that R6G-conjugated gold nanoparticles (AuNP) have a higher ROS quantum yield of 0.92 compared to 0.3 in an aqueous R6G solution, increasing their potency as PS. Cytotoxicity assessment on A549 cells and antibacterial assay on MDR Pseudomonas aeruginosa collected from a sewage treatment plant are the evidence to support efficient PDT. In addition to their enhanced quantum yields, the decorated particles are effective in generating fluorescent signals that can be used for cellular imaging and real-time optical imaging, and the presence of AuNP is a valuable addition to CT imaging. Furthermore, the fabricated particle exhibits anti-Stokes properties, which makes it suitable for use as a background-free biological imaging agent. As a result, R6G-conjugated AuNP is an effective theranostic agent that prevents the progression of cancer and MDR bacteria, along with contrasting abilities in medical imaging with minimal toxicity observed in in vitro and in vivo assays using zebrafish embryos.

Abstract
Background and purpose The reciprocal translocation of the ABL gene from chromosome 9 to chromosome 22 near the BCR gene gives rise to chronic myelogenous leukemia (CML). The translocation results in forming the Philadelphia chromosome (BCR-ABL) tyrosine kinase. CML results in an increase in the number of white blood cells and alteration in tyrosine kinase expression. CML prognosis includes three stages, namely chronic, accelerated, and blast. The diagnosis method involves a CT scan, biopsy, and complete blood count. However, due to certain disadvantages, early diagnosis of CML is not possible by traditional methods. Nanotechnology offers many advantages in diagnosing and treating cancer. Experimental approach We searched PubMed, Scopus and Google Scholar using the keywords Philadelphia chromosome, bionanotechnology, tyrosine kinase pathway, half-life, passive targeting, and organic and inorganic nanoparticles. The relevant papers and the classical papers in this field were selected to write about in this review. Key results The sensitivity and specificity of an assay can be improved by nanoparticles. Utilizing this property, peptides, antibodies, aptamers, etc., in the form of nanoparticles, can be used to detect cancer at a much earlier stage. The half-life of the drug is also increased by nanoformulation. The nanoparticle-coated drugs can easily escape from the immune system. Conclusion Depending on their type, nanoparticles can be categorized into organic, inorganic and hybrid. Each type has its advantages. Organic nanoparticles have good biocompatibility, inorganic nanoparticles increase the half-life of the drugs. In this review, we highlight the nanoparticles involved in treating CML.

Abstract
Background and purpose The pandemic of COVID-19 has highlighted the need for managing infectious diseases, which spreads by airborne transmission leading to serious health, social, and economic issues. SARS-CoV-2 is an enveloped virus with a 60-140 nm diameter and particle-like features, which majorly accounts for this disease. Expanding diagnostic capabilities, developing safe vaccinations with long-lasting immunity, and formulating effective medications are the strategies to be investigated. Experimental approach For the literature search, electronic databases such as Scopus, Google Scholar, MEDLINE, Embase, PubMed, and Web of Science were used as the source. Search terms like 'Nano-mediated PDT,' 'PDT for SARS-CoV-2', and 'Nanotechnology in treatment for SARS-CoV-2' were used. Out of 275 initially selected articles, 198 were chosen after the abstract screening. During the full-text screening, 80 papers were excluded, and 18 were eliminated during data extraction. Preference was given to articles published from 2018 onwards, but a few older references were cited for their valuable information. Key results Synthetic nanoparticles (NPs) have a close structural resemblance to viruses and interact greatly with their proteins due to their similarities in the configurations. NPs had previously been reported to be effective against a variety of viruses. In this way, with nanoparticles, photodynamic therapy (PDT) can be a viable alternative to antibiotics in fighting against microbial infections. The protocol of PDT includes the activation of photosensitizers using specific light to destroy microorganisms in the presence of oxygen, treating several respiratory diseases. Conclusion The use of PDT in treating COVID-19 requires intensive investigations, which has been reviewed in this manuscript, including a computational approach to formulating effective photosensitizers.

Abstract
Lung cancer is managed using conventional therapies, including chemotherapy, radiation therapy, or a combination of both. Each of these therapies has its own limitations, such as the indiscriminate killing of normal as well as cancer cells, the solubility of the chemotherapeutic drugs, rapid clearance of the drugs from circulation before reaching the tumor site, the resistance of cancer cells to radiation, and over-sensitization of normal cells to radiation. Other treatment modalities include gene therapy, immunological checkpoint inhibitors, drug repurposing, and in situ cryo-immune engineering (ICIE) strategy. Nanotechnology has come to the rescue to overcome many shortfalls of conventional therapies. Some of the nano-formulated chemotherapeutic drugs, as well as nanoparticles and nanostructures with surface modifications, have been used for effective cancer cell killing and radio sensitization, respectively. Nano-enabled drug delivery systems act as cargo to deliver the sensitizer molecules specifically to the tumor cells, thereby enabling the radiation therapy to be more effective. In this review, we have discussed the different conventional chemotherapies and radiation therapies used for inhibiting lung cancer. We have also discussed the improvement in chemotherapy and radiation sensitization using nanoparticles.

Abstract
Abstract:
Ingestion of microbial-contaminated food causes severe health issues due to the outburst of serious foodborne diseases. To prevent these situations, sensitive and precise detection of toxins and identification of pathogenic microbes are very important in today’s world. Different types of toxins include natural, chemical, and metal toxins. Based on their origin, natural toxins are classified into biotoxins which are produced by microorganisms (algal, bacteria, fungal), animal toxins, and phytotoxins. Researchers enabled the use of nanomaterials in biosensors, enhancing sensitivity, stability, and specificity. Nanomaterials like gold, silver, carbon nanotubes, graphene, magnetic nanoparticles, and quantum dots were commonly used to develop biosensors. Thus, this mini-review summarizes the old conventional and new analytical methods for detecting a few natural toxins present in different food samples.

Abstract
INTRODUCTION Overuse and improper dosage of antibiotics have generated antimicrobial resistance (AMR) worldwide. Pseudomonas aeruginosa (PA), a well-known bacterial strain can establish MDR leading to a variety of infections in humans. Furthermore, these PA strains hold the ability to form biofilms by generating extracellular polymeric substances on the surface of medical tools and critical care units. To supersede the infectious effect of MDR organisms, silver nanoparticles have been known to be the choice. MATERIALS AND METHODS Hence, the present study concentrates on the engineering of varying concentrations of gelatin-based polymeric hydrogel embedded with silver nanoparticles (G-AgNPs) for controlled bactericidal activity against MDR PA biofilms. Biofilms formation by MDR PA was confirmed microscopically and spectroscopy was taken as a tool to characterize and analyze the efficacy at every stage of experiments. RESULTS When MDR PA biofilms were treated with G-AgNPs prepared with 5 % gelatin concentration (AgNP3), they exhibited superior bactericidal activity. Furthermore, a dose-dependent study showed that 800 nM of AgNP3 could inhibit the growth of MDR PA. CONCLUSION Hence it can be concluded that silver nanoparticles synthesized in the presence of 5% gelatin can act as a bactericidal agent in the inactivation of MDR PA biofilms, thereby controlling the infections caused by these biofilms.

Abstract
Cancer is one of the significant issues with public health and the second leading cause of death worldwide. The three most lethal cancers in the general population are stomach, lung, and liver cancers, in which lung and breast cancers cause the majority of cancer-associated deaths among men and women, respectively. CeO2 nanoparticles have a cytoprotectant effect in normal cells and a cytotoxic effect in cancer cells that enables them to induce the reactive oxygen species (ROS) production within cancer cells, which in turn develops reactive nitrogen species (RNS) that interfere with intracellular activities, and this property makes them an excellent anticancer agent. Because of its biofilm suppression, free radical scavenging ability, redox activity, and other unique properties, attention has been bestowed on cerium oxide nanoparticles as a potential alternative to solve many biomedical issues in the future. This review mainly focuses on the combinatorial effect of cerium dioxide nanoparticles and Doxorubicin in cancer management.

Abstract
Nanoparticles (NPs) designed for various theranostic purposes have hugely impacted scientific research in the field of biomedicine, bringing forth hopes of a future revolutionized area called nanomedicine. A budding advancement in this area is the conjugation of various cell membranes onto nanoparticles to develop biomimetic cells called 'Nanodecoys' (NDs), which can imitate the functioning of natural cells. This technology of coating cell membranes on NPs has enhanced the working capabilities of nano-based techniques by initiating effective navigation within the bodily system. Due to the presence of multiple functional moieties, nanoparticles coated with cell membranes hold the ability to interact with complex biological microenvironments inside the body with ease. Although developed with the initial motive to increase the time of circulation in the bloodstream and stability by coating membranes of red blood cells, it has further outstretched a wide range of cell lines, such as mesenchymal stem cells, beta cells, thrombocytes, white blood cells, and cancer cells. Thus, these cells and the versatile properties they bring along with them open up a brand-new domain in the biomedical industry where different formulations of nanoparticles can be used in appropriate dosages to treat a plethora of diseases. This review comprises recent investigations of nanodecoys in biomedical applications.

Abstract
BACKGROUND Essential oils that are extracted from plants have shown beneficial effects on humans and animals, evidenced by traditional medicine. They possess many essential phytocomponents that act as antimicrobial agents, and most of them are safe for external usage. INTRODUCTION Lemongrass essential oil is extracted from the grass, such as Cymbopogon flexuosus, and is used for antimicrobial activity for a long time. The efficacy of this oil is limited due to the poor solubility and microbial penetration, easy vaporization, and lower stability. Nanoformulations and nanoencapsulations are nanotechnology fields that aim to improve the bioavailability of many natural compounds and enhance their stability. Lemongrass oil has also been nanoformulated as nanoemulsion, and various antimicrobial activities against various pathogens have been demonstrated, which are superior to free lemongrass oil. METHODOLOGY We have used the search engines PubMed and Google Scholar for the mentioned keywords and selected the recent references related to this topic. CONCLUSION In this review, we have discussed various antimicrobial properties of lemongrass essential oil nanoemulsion and its application, such as antibacterial, antifungal, pesticidal, food preservative, and antibiofilm activity.

Abstract
Abstract:
Oxidative stress is known to be generated within the organism by endogenous cellular mechanisms and can also be generated by external factors. Oxidative stress is known to be involved in various disease pathologies such as cancer, osteoarthritis, cardiovascular diseases, ageing etc. The chronic/acute exposure to oxidative stress can easily damage cellular integrity through damaging the cellular DNA, mitochondrial DNA, proteins and other organelles that leads to malfunctioning of organs in the process of ageing. Mitochondrial respiration is one of the causes involved in the production of reactive oxygen species while generating bioenergetics (ATP) that provides energy to the cell for maintaining the cellular integrity through the electron transport chain mechanism and on the other side it generates free-radicals which could cause damage to the cellular organelles and biomolecules. In relation with this context, longevity through calorie restriction method could be due to the generation of lower reactive oxygen species and age-related diseases in vivo but accelerating loss of brains grey matter that could be due to the depletion in energy. This is because, intracellular ATP is the vital source of energy, extracellular ATP acts as signalling molecules. Use of advanced technology such as nanotechnology for the internalization of extracellular ATP, and to use it as external source of energy could provide energy for maintaining cellular integrity, improve the healthy longevity status when combined with calorie restriction method. In this perspective article we have presented a brief overview and our hypothesis that suggest that the calorie restriction and extracellular ATP treatment could circumvent the mitochondrial pathway and alleviates oxidative stress thereby improving health and enhance longevity.

Abstract
Biofilm formation hinders the activity of antimicrobial drugs at the site of infections and any agent that can act on both Gram-positive and Gram-negative bacteria by inhibiting the bacterial growth and rupturing the biofilm is needed to manage infection. In the present study, we have synthesized zirconia nanoparticles (ZrO2 NPs) and copper doped zirconia nanoparticles (Cu-ZrO2 NPs) and characterized them using dynamic light scattering, X-ray diffractometry, and scanning electron microscopy (SEM). The size of the Cu-ZrO2 NPs drastically reduced compared to ZrO2 NPs, and the antimicrobial activity was studied against Gram-positive bacteria (Lactobacillus sp.) and Gram-negative bacteria (Pseudomonas aeruginosa), respectively. The synthesized Cu-ZrO2 NPs showed superior inhibitory action against Lactobacillus sp. compared to ZrO2 NPs, due to the negatively charged cell wall of Lactobacillus sp., which could attract readily the positively charged Cu-ZrO2 NPs, thereby inhibiting its activity. The biocompatibility was tested using XTT assay in FL cells, and the results demonstrated that Cu-ZrO2 NPs were nontoxic to mammalian cells. Hence, it could be proposed that the synthesized Cu-ZrO2 NPs possess possible biomedical applications and can be used as antibacterial agents without causing toxicity in mammalian cells.

Abstract
PURPOSE OF REVEIW The root cause of many diseases like CVD, cancer, and aging is free radicals which exert their effect by interfering with different metabolic pathways. The sources of free radicals can be exogenous, like UV rays from sunlight, and endogenous due to different metabolic by-products.In our body, there are defense mechanisms present, such as antioxidant enzymes and antioxidant molecules to combat these free radicals, but if there is an overload of these free radicals in our body, the defense system may not be sufficient to neutralize these free radicals. In such situations, we are exposed to a chronic low dose of oxidants creating oxidative stress, which is responsible for eliciting different diseases. RECENT FINDINGS Pubmed and Google Scholar are the search engines used to sort out relevant papers on myricetin and its role in combating many diseases. Myricetin is present in many fruits and vegetables and is a known antioxidant. It can elevate the antioxidant enzyme levels; reduces the lipid peroxidation; and is known to protect against cancer. In the case of myocardial dysfunction, myricetin has been shown to suppress the inflammatory cytokines and reduced the mortality rate. Myricetin has also been found to reduce platelet aggregation and control the viral infections by interfering in the DNA replication pathways. SUMMARY In this paper, we have briefly reviewed about the different type and site of free radicals and the role of myricetin in addressing the ROS and different diseases.

Abstract
The importance of stem cell growth and its fate is highly essential for the use of stem cells in therapy and regeneration. There are conflicting evidences regarding the actual role of stem cells when injected into a patient towards damage recovery and its lifespan inside the body. Tumor microenvironment differs from that of normal cells and may have a role in the growth of stem cells when associated with them. In cancer, the uncontrolled growth of cells remodels the extracellular matrix (ECM). The ECM alteration occurs as the mutated fibroblast cells release growth factors into the ECM which further alters the ECM directly or changes the epithelial cells and then alters the ECM. In this review we will discuss about the components and functions of ECM and how does it differ in cancer cells compared to normal cells. Abnormal dynamics of the ECM and its role in cancer progression will also be discussed. Graphical abstract.

Abstract
Molecular imaging has gained utmost importance in the recent past in early diagnosis of diseases. In comparison to other imaging modalities, magnetic resonance imaging (MRI) has proven to extend its abilities not only for its usage of non-ionizing radiation but also for the high spatial resolution in soft tissues. A major limitation faced by MRI is the sensitivity in detecting diseased conditions until a certain stage. At present, this limitation is overcome with the use of contrast agents that show potential in altering the T1 and T2 relaxation times of the hydrogen protons. This modulation to the relaxation times leads to better contrast differences based on the type of contrast agent and the pulse sequence being engaged for acquiring images. Water molecules, as the major contributor of hydrogen protons, are proven to interact with such contrast agents. Major drawbacks noted with the marketed MRI contrast agents are their toxicity and renal clearance. To conquer these issues, magnetic nanomaterials are being researched for their abilities to match the contrast enhancement offered by traditional agents reducing their drawbacks. Furthermore, comparative diagnosis with both T1 and T2 contrast at the same time has also interested investigators. To achieve this, twin mode T1 and T2 weighted contrast agents are developed utilizing the remarkable properties extended by magnetic nanoplatforms. As a step forward, multimodal imaging agents are also being engineered based on these magnetic nanoplatforms that will generate cross-verified diagnoses using multiple imaging modalities with a unique imaging agent. This review starts by introducing the basics of MRI with major focus on the typical interactions of water molecules with a variety of magnetic nanomaterials. The review also concentrates on the clinical needs and nanomaterials available for twin T1 and T2 contrast with a minor introduction to multimodal imaging agents. In conclusion, the advent of MRI with the advantages offered by magnetic nanomaterials is summarized, leading to insights for future developments.

Abstract
The protein misfolded structure called amyloids is related with extensive range of pathologies like local amyloidosis and neurodegenerative diseases. Several studies have reported the potential of insulin to generate local amyloidosis under certain state. Reports also showed that fibrils of insulin generated local amyloid mass due to continuous subcutaneous injection in mouse as well as rat. The present study was designed to examine the consequence of insulin fibril injections in rats, as well as the ability of enzymes, Lumbrokinase (LK) and Serratiopeptidase (SP) in diminishing this amyloid mass progression. The results showed that insulin fibrils generated amyloid masses in rats after subcutaneous injection for two weeks which was significantly condensed in size for the groups injected with insulin fibrils combined with LK or SP. At higher doses of LK and SP, the absence of amyloid structure was observed in histopathological studies. Light microscopy, polarized microscopy as well as Lumia live in vivo imaging system was used to analyze the results. In conclusion, the overall outcome of this study showed the anti-amyloid potential of enzyme LK and SP in the attenuation of local amyloidosis.

Abstract
BACKGROUND PrPC is a host-encoded prion protein, which gets post translationally modified into a transmissible, β-sheet rich disease associated protein called PrPSc, responsible for the Prion disease including mad cow disease in cattle and CJD in humans. The PrP 106-126 region in PrPSc peptide initiates the conformational change in that protein leading to fibrillation. Any agent that can destabilize or disintegrate such proteins can be served as a potential drug candidate for Prion diseases. METHODS In the present study, an enzyme Lumbrokinase (LK) was isolated from earthworm and its activity was exploited towards PrP 106-126 amyloids in vitro along with another enzyme Serratiopeptidase (SP) taking Nattokinase (NK) as a standard. RESULTS The results showed that PrP 106-126 amyloid formation was inhibited by both LK and SP, as evidenced from Thioflavin T fluorescence assay. Further, the size of fibrils as estimated by dynamic light scattering, was also found to be lower at different time intervals after incubation of the prion amyloids with LK and SP. Additionally, the molecular dynamics simulation revealed the thermodynamically favorable interaction of PrP 106-126 with LK as well as with SP with high affinity. CONCLUSION Finally, the toxicity of the disintegrated amyloids was assessed using PC12 cell lines which showed higher cell viability in case of LK and SP treated amyloids compared to only PrP 106- 126 amyloid treatment. Altogether, the study concluded that the serine proteases like LK and SP have the potential to disintegrate PrP 106-126 amyloids with improved cell viability. The in vivo studies are needed to be executed in future.

Abstract
Owing to the limitations of conventional therapies, there has been an increasing need for nanomedicines for real-time diagnosis and effective treatment of life-threatening diseases. Despite the conceptual and technological success achieved by researchers worldwide, the complexities of biological systems, efficient engineering and formulation of monodispersed nanomedicines, inadequate information on bio–nano interactions, issues on health hazards, clinical trials and commercialization have set new challenges in biomedical research. This review highlights how the biological membrane improves the performance of nanomedicines in drug delivery. With the list of nanomedicines getting longer gradually to overcome the drawbacks of conventional therapeutics, it is important to concentrate on the interactions between nanostructures and living systems in order to improve the biocompatibility and therapeutic efficacy of functional nanomedicines.

Abstract
OBJECTIVE The label free ultrasmall fluorescent ferrite clusters have been engineered in a controlled fashion which was stabilized by serum protein and functionalized by folic acid for the application of targeted multimodal optical and Magnetic Resonance (MR) cancer imaging. METHODS The ultra-small manganese ferrite nanoclusters (PMNCs) with a diameter of 4 nm have a commendable effect on the longitudinal (T1) and transverse (T2) relaxation in MR imaging that was evident from the phantom and animal MRI. RESULTS The calculated longitudinal molar relaxivity of nanoclusters was found to be 6.9 ± 0.10 mM-1 S-1 which was exactly 2.22 times better than the conventional Gd-DOTA and their 4.01 ratio of the transverse (r2) and longitudinal (r1) relaxivities made them a potential candidate for both T1 and T2 contrast agents in MRI. In addition, the fluorescence-based small animal imaging showed folic acid driven accumulated fluorescent signal at the tumour site to conclude the capacity of PMNCs for targeted fluorescence imaging of cancer diagnosis. CONCLUSION The cytotoxicity assay and histopathology studies were the evidence for their safe biodistribution in animal systems. Furthermore, the protein encapsulated clusters have the ability to deliver the anticancer drug Methotrexate (MTX) to the cancer tissues with a sustained manner. Therefore, one can conclude the remarkable efficacy of architect nanoclusters for theragnosis.

Abstract
The present study shows the thorough investigations on optical properties and hydrodynamic diameters of glutathione (GSH) stabilized nanosilver clusters (AgNC) at different stages of synthesis and engineering for the optimized absolute quantum yield to generate fluorescent images of Dalton Lymphoma Ascites (DLA) tumour bearing mice. The initial increment of quantum yield was wavelength dependent and finally it became 0.509 which was due to the camouflaging or entrapment of AgNC in macrophages membranes. The potentiality of macrophages membrane camouflaged silver nanoclusters (AgM) was reflected in the cell viability assay and confocal based live dead cell assay where the AgM has better cell killing effect compared to AgNC with reduced dosage and in vivo mice imaging generated the clear visualization at the tumour sites. Therefore, from the present study, it can be considered that the camouflaged nanosilver can be used for targeted theranostic applications.

Abstract
BACKGROUND Biopolymeric nanoparticles comprising chitosan-alginate have attracted interest in drug delivery due to their protective nature, biocompatibility, biodegradability and hydrophilicity. OBJECTIVE The present study was designed to encapsulate levofloxacin in chitosan-alginate hybrid gel for controlled release and to evaluate the effect of divalent alkaline earth metal ions (Mg2+, Ca2+, Sr2+, Ba2+) on encapsulation efficiency and drug release kinetics considering their role in polyelectrolyte gelation method. METHOD Divalent metal ions control the rigidity and elasticity of the hydrogels and have the ability to change the shape and size of nanostructure formed by chitosan-alginate. The particle size increases and encapsulation efficiency decreases with the size of the divalent ions. Spherical shaped particles were formed by Mg2+ and Ca2+, whereas Sr2+ and Ba2+ produced non-spherical particles. RESULTS SEM image clearly shows transformation of sphere to truncated tetrahedron by Sr2+ and clear rod shape by Ba2+. CONCLUSION Therefore, it is concluded that metal ions have significant influence on the morphology and drug encapsulation and release profile of the chitosan-alginate hybrid polymer nanoparticles.

Abstract
In the present work, an attempt was made to engineer a mesoporous silica coated magnetic nanoparticles (MNF@mSiO2) for twin mode contrast in magnetic resonance imaging (MRI) with reduced toxicity. Superparamagnetic manganese ferrite nanoparticles were synthesized with variable mesoporous silica shell thickness to control the water molecules interacting with metal oxide core. 178 nm was the optimum hydrodynamic diameter of mesoporous ferrite core-shell nanoparticles that showed maximum longitudinal relaxation time (T1) and transverse relaxation time (T2) in MRI due to the storage of water molecules in mesoporous silica coating. Besides the major role of mesoporous silica in controlling relaxivity, mesoporous silica shell also reduces the toxicity and enhances the bioavailability of superparamagnetic manganese ferrite nanoparticles. The in vitro toxicity assessment using HepG2 liver carcinoma cells shows that the mesoporous silica coating over ferrite nanoparticles could exert less toxicity compared to the uncoated particle.

Abstract
Zinc oxide (ZnO) is explicitly used in sunscreens and cosmetic products; however, its effect in vivo is toxic in some cases. The UV blocking efficacy of ZnO nanoparticles is lost due to photocatalysis. To isolate a lower toxic species of sunblockers, ZnO nanoparticles were synthesized and coated with chitosan - a natural polymer (ZnO-CTS) and polyethylene glycol (PEG) - a synthetic polymer (ZnO-PEG). Coating with CTS and PEG circumvented the photocatalytic activity, increased the stability and improved the UV absorption efficacy. The effect of ZnO, ZnO-CTS and ZnO-PEG nanoparticles in vivo on zebrafish embryo revealed lower deposition of ZnO-CTS and ZnO-PEG nanoparticles atop the eggs compared to ZnO. The survival of zebrafish embryos was always found to be higher in case of ZnO-CTS with respect to ZnO-treated ones. PEG coating exhibited better UV attenuation, but, in vivo it induced delayed hatching. Thus, one of the reasons for better survival could be attributed to lower aggregation of ZnO-CTS nanoparticles atop eggs thereby facilitating the breathing of embryos.

Abstract
We derived V79(C) cells from V79 cell line through chronic oxidative stress by H2O2. These cells demonstrated transformation-like stable changes. Our objective was to see how V79(C) cells would respond to cisplatin treatment and also to understand the mechanism of cisplatin-resistance, because resistance towards various chemotherapeutic agents is major cause of concern in cancer therapeutics. The sensitivity to cisplatin in these cells was observed by comparing the viability with that of parental V79 cells from colonogenic assay. The role of apoptotic death was investigated microscopically by Hoechst staining and from nucleosomal ladder formation in agarose gel. Release of cytochrome c from the mitochondria was determined by Western blotting. Caspase 9 and caspase 3 activities were estimated through fluorimetric assay. We found that V79(C) cells exhibited lower sensitivity towards killing by cisplatin through suppression of apoptotic cell death. Quantifying the release of cytochrome c in the cytoplasm and assay of caspase 9 and caspase 3 activities revealed that cisplatin resistance was due to inhibition of caspase-dependent apoptotic death pathways. These findings may aid in understanding the mechanism of cisplatin resistance in tumors arising from oxidative stress. Exogenous caspases may facilitate apoptotic death to sensitize such resistant cells.

Abstract
In prion diseases, the posttranslational modification of host-encoded prion protein PrP(c) yields a high beta-sheet content modified protein PrP(sc), which further polymerizes into amyloid fibrils. PrP106-126 initiates the conformational changes leading to the conversion of PrP(c) to PrP(sc). Molecules that can defunctionalize such peptides can serve as a potential tool in combating prion diseases. In microorganisms during stressed conditions, small stress molecules (SSMs) are formed to prevent protein denaturation and maintain protein stability and function. The effect of such SSMs on PrP106-126 amyloid formation is explored in the present study using turbidity, atomic force microscopy (AFM), and cellular toxicity assay. Turbidity and AFM studies clearly depict that the SSMs-ectoine and mannosylglyceramide (MGA) inhibit the PrP106-126 aggregation. Our study also connotes that ectoine and MGA offer strong resistance to prion peptide-induced toxicity in human neuroblastoma cells, concluding that such molecules can be potential inhibitors of prion aggregation and toxicity.
