Abstract
This study aimed to synthesize and characterize DTX-mPEG-PLA-NPs along with the development and validation of a simple, accurate, and reproducible method for the determination and quantification of DTX in mPEG-PLA-NPs. The prepared NPs were characterized using AFM, DLS, zetasizer, and drug release kinetic profiling. The RP-HPLC assay was developed for DTX detection. The cytotoxicity and anti-clonogenic effects were estimated using MTT and clonogenic assays, respectively, using both MCF-7 and MDA-MB-231 cell lines in a 2D and 3D culture system. The developed method showed a linear response, high precision, accuracy, RSD values of ≤2%, and a tailing factor ≤2, per ICH guidelines. The DTX-mPEG-PLA-NPs exhibited an average particle size of 264.3 nm with an encapsulation efficiency of 62.22%. The in vitro drug kinetic profile, as per the Krosmeyers-Peppas model, demonstrated Fickian diffusion, with initial biphasic release and a multistep sustained release over 190 h. The MTT assay revealed improved in vitro cytotoxicity against MCF-7 and MDA-MB-231 in the 2D cultures and MCF-7 3D mammosphere cultures. Significant inhibitions of the clonogenic potential of MDA-MB-231 were observed for all concentrations of DTX-mPEG-PLA-NPs. Our results highlight the feasibility of detecting DTX via the robust RP-HPLC method and using DTX-mPEG-PLA-NPs as a perceptible and biocompatible delivery vehicle with greater cytotoxic and anti-clonogenic potential, supporting improved outcomes in BC.

Abstract
Neurological diseases are one of the most pressing issues in modern times worldwide. It thus possesses explicit attention from researchers and medical health providers to guard public health against such an expanding threat. Various treatment modalities have been developed in a remarkably short time but, unfortunately, have yet to lead to the wished-for efficacy or the sought-after clinical improvement. The main hurdle in delivering therapeutics to the brain has always been the blood-brain barrier which still represents an elusive area with lots of mysteries yet to be solved. Meanwhile, nanotechnology has emerged as an optimistic platform that is potentially holding the answer to many of our questions on how to deliver drugs and treat CNS disorders using novel technologies rather than the unsatisfying conventional old methods. Nanocarriers can be engineered in a way that is capable of delivering a certain therapeutic cargo to a specific target tissue. Adding to this mind-blowing nanotechnology, the revolutionizing gene-altering biologics can have the best of both worlds, and pave the way for the long-awaited cure to many diseases, among those diseases thus far are Alzheimer's disease (AD), brain tumors (glioma and glioblastoma), Down syndrome, stroke, and even cases with HIV. The review herein collects the studies that tested the mixture of both sciences, nanotechnology, and epigenetics, in the context of brain therapeutics using three main categories of gene-altering molecules (siRNA, miRNA, and CRISPR) with a special focus on the advancements regarding the new favorite, intranasal route of administration.

Abstract
Monitoring tumor progression is important for elucidating appropriate therapeutic strategies in response to anticancer therapeutics. To fluorescently monitor the in vivo levels of tumor-specific enzymes, we prepared matrix metalloprotease (MMP)-responsive gold nanoparticle (AuNP) clusters to sense tumor microenvironments. Specifically, AuNPs and quantum dots (QDs) were surface-engineered with two poly(ethylene glycol) [PEG] shells and cyclooctyne moieties, respectively, for the copper-free click reaction. Upon "peeling off" of the secondary shell from the double-PEGylated AuNPs under MMP-rich conditions, shielded azide moieties of the AuNPs were displayed toward the QD, and those two particles were clicked into nanoparticle clusters. This consequently resulted in a dramatic size increase and fluorescence quenching of QDs via fluorescence energy transfer (FRET) due to the molecular proximity of the particles. We observed that FRET efficiency was modulated via changes in MMP levels and exposure time. Cancer cell numbers exhibited a strong correlation with FRET efficiency, and in vivo studies that employed solid tumor models accordingly showed that FRET efficiency was dependent on the tumor size. Thus, we envision that this platform can be tailored and optimized for tumor monitoring based on MMP levels in solid tumors.

Abstract
Nanoformulation based drug delivery is one of the most important research areas in the field of nanomedicine, which provides promising alternatives to the limitations of conventional chemotherapy. Nano drug delivery enables improved pharmacokinetic profile, bioavailability and therapeutic efficiency compared to the regular chemotherapeutic drugs. Herein, we have established a simple method for the synthesis of docetaxel (Dtx) encapsulated poly (ethylene glycol) (PEG) functionalized gold nanoparticles (AuNPs) for targeted drug delivery to prostate cancer. AuNPs were synthesized by the citrate ion reduction method followed by functionalization with thiol-PEG-amine (SH-PEG-NH2). SH-PEG-NH2 functionalized AuNPs were conjugated with the targeting vehicle, folic acid (FA). The anticancer drug, Dtx was encapsulated within AuNPs by the non-covalent linkage method. The physicochemical characteristics of the synthesized nanoformulations were extensively characterized by various spectral and microscopic studies. HR-TEM indicates the average size of the AuNPs is 16 nm and the nanoformulations is 18 nm. The encapsulation efficiency of the Dtx is ~ 96% which is confirmed by the elemental mapping analysis. The in vitro drug release profile of Dtx and AuNPs nanoformulations were studied by the dialysis membrane method. The anticancer activity of docetaxel encapsulated AuNPs were evaluated with prostate cancer cell lines (PC3). The drug encapsulated nanoformulations reduced the cell viability to about 40% (40 µM concentration at 24, 48 and 72 h of treatment). The optical microscopy observation reveals that the damage of prostate cancer cells after exposure to Dtx encapsulated AuNPs. The good cytotoxic activity of the present nanoformulation against prostate cancer cell lines enables its application for targeted drug delivery to prostate cancer.

Abstract
Nanoparticles (NPs) represent a major point of interest in the scientific field, with an increasing number of studies revealing promising results. Nano-oncology is a relatively new area of research that continues to expand, revealing new perspectives in both diagnosing and treating cancer. Treating pancreatic cancer (PC) remains a major challenge, with modest positive results, thus an increasing number of studies have focused on this disease. Out of all the NPs that have been used in experimental studies, gold NPs (GNPs) appear to be the most efficient, with little systemic toxicity. This review aims to summarize the latest studies that reveal the effects that GNPs have on PC cells, focusing on different ways in which they can be used to diagnose this disease, to induce apoptosis or cause cytotoxicity in cancer cells. Although literature has limited data concerning this specific topic, the results are promising. However more studies are required until GNPs can be used in clinical practice.

Abstract
Prostate cancer (PCa) is the leading cause of death by cancer in men. Because of the drastic decline in the survival rate of PCa patients with advanced/metastatic disease, early diagnosis of disease and therapy without toxic side effects is crucial. Chemotherapy is widely used to control the progression of PCa at the later stages; however, it is associated with off-target toxicities and severe adverse effects due to the lack of specificity. Delivery of therapeutic or diagnostic agents by using targeted nanoparticles is a promising strategy to enhance accuracy and sensitivity of diagnosis of PCa and to increase efficacy and specificity of therapeutic agents. Numerous efforts have been made in past decades to create nanoparticles with different architectural bases for specific delivery payloads to prostate tumors. Major PCa associated cell membrane protein markers identified as targets for such purposes include folate receptor, sigma receptors, transferrin receptor, gastrin-releasing peptide receptor, urokinase plasminogen activator receptor, and prostate specific membrane antigen. Among these markers, prostate specific membrane antigen has emerged as an extremely specific and sensitive targetable marker for designing targeted nanoparticle-based delivery systems for PCa. In this article, we review contemporary advances in design, specificity, and efficacy of nanoparticles functionalized against PCa. Whenever feasible, both diagnostic as well as therapeutic applications are discussed.

Abstract
The rapid electrochemical identification and quantification of neurotransmitters being a challenge in the ever-growing field of neuroelectronics, we aimed to facilitate the electrochemical selective detection of dopamine by functionalizing commercially available electrodes through the deposition of a thin film containing pre-formed gold nanoparticles. The influence of different parameters and experimental conditions, such as buffer solution, fiber material, concentration, and cyclic voltammetry (CV) cycle number, were tested during neurotransmitter detection. In each case, without drastically changing the outcome of the functionalization process, the selectivity towards dopamine was improved. The detected oxidation current for dopamine was increased by 92%, while ascorbic acid and serotonin oxidation currents were lowered by 66% under the best conditions. Moreover, dopamine sensing was successfully achieved in tandem with home-made triple electrodes and an in-house built potentiostat at a high scan rate mode.

Abstract
The effective use of the gold nanoparticle (AuNPs) conjugated drugs for targeted drug delivery applications is one of the most promising research areas in the field of cancer. Herein, we aimed to establish a nano drug conjugated with docetaxel as a possible therapy option. Gold nanoparticles were synthesized by chemical reduction method. This is followed by the conjugation with an anticancer drug, docetaxel (Dtx) by a non-covalent method and folic acid (FA) was conjugated by a covalent method. The physicochemical characteristics of the synthesized AuNPs, Dtx and FA were studied by various analytical techniques such as UV-vis spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscope (FE-SEM) high-resolution transmission electron microscope (HR-TEM) and energy dispersive X-ray spectroscopy (EDS). The surface morphology and microstructure of the synthesized AuNPs and gold conjugates (AuNPs-Dtx-FA) were examined by FESEM and HR-TEM. The average size of the spherical shaped AuNPs was observed in the range of 5-18 nm. XPS and EDS spectra were examined the oxidation state and chemical composition of the synthesized nanoparticles. The cytotoxicity of the synthesized AuNPs nano-conjugates was evaluated by in-vitro studies against lung cancer cell line (H520). The chemical reduction method followed here in the development of AuNPs is a simple and one-step process, which exhibits the excellent binding specificity, biocompatibility and feasible for the large scale up process of the AuNPs.

Abstract
A microfluidic-based spectrophotometer for neurotransmitters sensing is presented in this paper. In addition, a neurotransmitter photo-fingerprint is analyzed to evaluate the feasibility of selective neurotransmitter detection using optical techniques. The aim of this work is to detect major neurotransmitters (NTs) using a compact, portable and cost effective optical system for selective and real time NT concentration monitoring. Micro-spectroscopic detection of NTs is challenging because most of them are transparent to visible light. Nevertheless, they interfere with the absorption spectrum of gold nanoparticles (Au-NP), which exhibit maximum absorbance in the range of 520 nm. We observed an Au-NP maximum absorbance shift of up to 4nm in presence of NTs. Based on this shift, it is possible to detect NTs using visible ligh by using vertical-cavity surface-emitting laser (VCSEL) as light sources and an integrated system-on-chip (SoC) spectrophotometer.

Abstract
A large number of drugs are administered on different mucosal surfaces. However, due to the poor mucoadhesion of the current formulations, their bioavailability is often very low. The development of efficient mucoadhesive drug delivery systems is thus crucial for improving the performance of these drugs. The mucoadhesive properties of gold nanoparticles were investigated. First, two types of gold nanoparticles were synthesized: AuNP1 and AuNP2. AuNP1 only contain internal thiol groups on their metallic core, and AuNP2 contain both internal and peripheral thiol groups. Different protocols based on an adapted quantitative colorimetric method, UV-visible and fluorescence spectroscopies were then developed to gather information on their mucoadhesive properties. Moreover, a global correction factor for the inner filter effect in spectrofluorimetry was proposed, and the data obtained were compared to those commonly used in the literature. Mucins deeply interact with AuNP1, perturbing their core, whereas they remain at the periphery of AuNP2. The quantitative method suggests that a larger number of mucins interact with AuNP2. The establishment of this protocol could be applied to assess the mucoadhesive properties of other stable molecules. This mucoadhesive property of gold nanoparticles could be combined with their drug delivery ability in order to improve the medication administered on mucosa.

Abstract
Gold nanoparticles are commonly used for medical applications such as drug delivery and as therapeutic and diagnostic materials because of their unique properties. In this study, we prepared docetaxel (DTX)-loaded hyaluronic acid-cleavable-peptide-gold nanoparticles for the treatment of cancer by selectively delivering DTX into the tumor and, thus, enhancing the therapeutic effect of DTX; further, we determined synergistic effects of the nanoparticles using laser treatment. The DTX-loaded hyaluronic acid-cleavable-peptide-gold nanoparticles prepared in this study had an average size of 75 nm and negative surface charge. The nanoparticles revealed greater cytotoxicity and higher tumor suppression efficacy in tumor models than free DTX under near-infrared laser irradiation. Therefore, the nanoparticle formulation prepared in this study could be utilized for targeted drug delivery and in combination with other cancer therapies.

Abstract
AIM Therapeutic efficacy of anticancer nanomedicine is compromised by tumor stromal barriers. The present study deals with the development of docetaxel loaded PEGylated liposomes (DTXPL) and to investigate the effect of tumor stroma disrupting agent, telmisartan, on anticancer efficacy of DTXPL. METHODS DTXPL was prepared using proprietary modified hydration method. Effect of oral telmisartan treatment on tumor uptake of coumarin-6 liposomes and anticancer efficacy of DTXPL was evaluated in orthotopic xenograft lung tumor bearing mice. RESULTS DTXPL (105.7 ± 3.8 nm) showed very high physical stability, negligible hemolysis, 428% enhancement in bioavailability with significantly higher intratumoral uptake. Marked reduction in collagen-I, MMP2/9 and lung tumor weight were observed in DTXPL+telmisartan group. CONCLUSION Combination of DTXPL with telmisartan could significantly enhance clinical outcome in lung cancer.

Abstract
Worldwide research groups are searching for anticancer compounds, many of them are organometalic complexes having platinum group metals as their active centers. Most commonly used cytostatics from this group are cisplatin, carboplatin and oxaliplatin. Cisplatin was used fot the first time in 1978, from this time many platinum derivatives were created. In this review we present biological properties and probable future clinical use of platinum, gold, silver, iridium and ruthenium derivatives. Gold derivative Auranofin has been studied extensively. Action of silver nanoparticles on different cell lines was analysed. Iridium isotopes are commonly used in brachyterapy. Ruthenium compound new anti-tumour metastasis inhibitor (NAMI-A) is used in managing lung cancer metastases. Electroporation of another ruthenium based compound KP1339 was also studied. Most of described complexes have antiproliferative and proapoptotic properties. Further studies need to be made. Nevertheless noble metal based chemotherapheutics and compounds seem to be an interesting direction of research.

Abstract
Docetaxel is one of the most active chemotherapeutic agents for cancer treatment. The traditional docetaxel injection (TAXOTERE®) is currently formulated in the surfactant polysorbate 80, which has been associated with severe adverse reactions. To avoid the use of polysorbate 80 as well as to reduce the systemic toxicity of docetaxel, in this study, docetaxel-loaded albumin nanoparticles were fabricated by a novel simple self-assembly method. The resulting nanoparticles showed a mean diameter size of 150 nm. After being encapsulated into nanoparticles, docetaxel displayed similar cytotoxicity to traditional injection. Since polysorbate 80 was not involved in nanoparticles, the hemolysis was completely eliminated. The maximal tolerance dose of nanoparticles was also increased, which allowed a higher dose to be safely intravenously injected and produced ideal antitumor effects. The 150 nm diameter also allowed the nanoparticles to accumulate in tumor tissue via the enhanced permeability and retention effect. The passive targeting ability further caused the higher antitumor effects of nanoparticles than that of traditional injection at the same dose (7.5 mg/kg). Therefore, docetaxel-loaded albumin nanoparticles fabricated by our strategy showed higher promise in their safety and effectiveness than the traditional docetaxel injection.

Abstract
Background Feline injection-site sarcomas are malignant skin tumors of mesenchymal origin, the treatment of which is a challenge for veterinary practitioners. Methods of treatment include radical surgery, radiotherapy and chemotherapy. The most commonly used cytostatic drugs are cyclophosphamide, doxorubicin and vincristine. However, the use of cytostatics as adjunctive treatment is limited due to their adverse side-effects, low biodistribution after intravenous administration and multidrug resistance. Colloid gold nanoparticles are promising drug delivery systems to overcome multidrug resistance, which is a main cause of ineffective chemotherapy treatment. The use of colloid gold nanoparticles as building blocks for drug delivery systems is preferred due to ease of surface functionalization with various molecules, chemical stability and their low toxicity. Methods Stability and structure of the glutathione-stabilized gold nanoparticles non-covalently modified with doxorubicin (Au-GSH-Dox) was confirmed using XPS, TEM, FT-IR, SAXRD and SAXS analyses. MTT assay, Annexin V and Propidium Iodide Apoptosis assay and Rhodamine 123 and Verapamil assay were performed on 4 feline fibrosarcoma cell lines (FFS1WAW, FFS1, FFS3, FFS5). Statistical analyses were performed using Graph Pad Prism 5.0 (USA). Results A novel approach, glutathione-stabilized gold nanoparticles (4.3 +/- 1.1 nm in diameter) non-covalently modified with doxorubicin (Au-GSH-Dox) was designed and synthesized. A higher cytotoxic effect (p<0.01) of Au-GSH-Dox than that of free doxorubicin has been observed in 3 (FFS1, FFS3, FFS1WAW) out of 4 feline fibrosarcoma cell lines. The effect has been correlated to the activity of glycoprotein P (main efflux pump responsible for multidrug resistance). Conclusions The results indicate that Au-GSH-Dox may be a potent new therapeutic agent to increase the efficacy of the drug by overcoming the resistance to doxorubicin in feline fibrosarcoma cell lines. Moreover, as doxorubicin is non-covalently attached to glutathione coated nanoparticles the synthesized system is potentially suitable to a wealth of different drug molecules.

Abstract
Prostate cancer is the most common non-cutaneous malignancy in American men. Docetaxel is a useful chemotherapeutic agent for prostate cancer that has been available for over a decade, but the length of the treatment and systemic side effects hamper compliance. Additionally, docetaxel resistance invariably emerges, leading to disease relapse. Docetaxel resistance is either intrinsic or acquired by adopting various mechanisms that are highly associated with genetic alterations, decreased influx and increased efflux of drugs. Several combination therapies and small P-glycoprotein inhibitors have been proposed to improve the therapeutic potential of docetaxel in prostate cancer. Novel therapeutic strategies that may allow reversal of docetaxel resistance include alterations of enzymes, improving drug uptake and enhancement of apoptosis. In this review, we provide the most current docetaxel reversal approaches utilizing nanotechnology. Nanotechnology mediated docetaxel delivery is superior to existing therapeutic strategies and a more effective method to induce P-glycoprotein inhibition, enhance cellular uptake, maintain sustained drug release, and improve bioavailability.
