Abstract
The need for excellent, affordable, rapid, reusable and biocompatible protein purification techniques is justified based on the roles of proteins as key biomacromolecules. Magnetic nanomaterials nowadays have become the subject of discussion in proteomics, drug delivery, and gene sensing due to their various abilities including rapid separation, superparamagnetism, and biocompatibility. These nanomaterials also referred to as magnetic nanoparticles (MNPs) serve as excellent options for traditional protein separation and analytical methods because they have a larger surface area per volume. From ionic metals to carbon-based materials, MNPs are easily functionalized by modifying their surface to precisely recognize and bind proteins. This review excavates state-of-the-art MNPs and their functionalizing agents, as efficient protein separation and purification techniques, including ionic metals, polymers, biomolecules, antibodies, and graphene. The MNPs could be reused and efficaciously manipulated with these nanomaterials leading to highly improved efficiency, adsorption, desorption, and purity rate. We also discuss the binding and selectivity parameters of the MNPs, as well as their future outlook. It is concluded that parameters like charge, size, core-shell, lipophilicity, lipophobicity, and surface energy of the MNPs are crucial when considering protein selectivity, chelation, separation, and purity.

Abstract
Recently, microRNAs (miRNA) captured the interest as novel diagnostic and prognostic biomarkers, with their potential for early indication of numerous pathologies. Since miRNA is a short, non-coding RNA sequence, the sensitivity and selectivity of their detection remain a cornerstone of scientific research. As such, methods based on nanomaterials have emerged in hopes of developing fast and facile approaches. At the core of the detection method based on nanotechnology lie nanoprobes and other functionalized nanomaterials. Since miRNA sensing and detection are generally rooted in the capture of target miRNA with the complementary sequence of oligonucleotides, the sequence needs to be attached to the nanomaterial with a specific conjugation strategy. As each nanomaterial has its unique properties, and each conjugation approach presents its drawbacks and advantages, this review offers a condensed overview of the conjugation approaches in nanomaterial-based miRNA sensing. Starting with a brief recapitulation of specific properties and characteristics of nanomaterials that can be used as a substrate, the focus is then centered on covalent and non-covalent bonding chemistry, leading to the functionalization of the nanomaterials, which are the most commonly used in miRNA sensing methods.

Abstract
MicroRNAs (miRNAs) are small non-coding RNAs that play a role in regulating gene expression. MiRNAs are focused on as potential cancer biomarkers due to their involvement in the cancer development. New effective techniques for extracting miRNA from a biological matrix is important. Recently, graphene quantum dots (GQDs) have been used to detect DNA/RNA in many sensor platforms, but the application in miRNA extraction remains limited. To extract miRNAs, the miRNA adsorption and desorption on GQD are the key. Thus, in this work, the adsorption mechanism of excess miRNA on GQD in solution is revealed using Molecular dynamics simulations. The miRNA assemblies on one and two GQDs were studied to explore the possibility of using GQD for miRNA extraction. The folded miR-29a molecule, one of key cancer biomarkers, is used as an miRNA model. Three systems with one (6miR) and two GQDs (with parallel (6miR_2GP) and sandwich (6miR_2GS) organisations) in six-miR-29a solution were set. The data show excess miR-29a can reduce the miR-29a-GQD binding efficiency. The opening of intrabase pairing of GQD-absorbed miR-29a facilitates the interbase coupling resulting in the self-aggregation of miR-29a. The GQD organisation also affects the miR-29a adsorption ability. The additional GQDs result in the tighter miR-29a adsorption which can retard the miR-29a desorption. The proper GQD concentration is thus important to successfully collect all miR-29a and accommodate the easy miR-29a dissociation. Our results can be useful for a design of DNA probe and choosing decent nanosized GRA concentration for experimental setups.

Abstract
High-quality point-of-care is critical for timely decision of disease diagnosis and healthcare management. In this regard, biosensors have revolutionized the field of rapid testing and screening, however, are confounded by several technical challenges including material cost, half-life, stability, site-specific targeting, analytes specificity, and detection sensitivity that affect the overall diagnostic potential and therapeutic profile. Despite their advances in point-of-care testing, very few classical biosensors have proven effective and commercially viable in situations of healthcare emergency including the recent COVID-19 pandemic. To overcome these challenges functionalized magnetic nanoparticles (MNPs) have emerged as key players in advancing the biomedical and healthcare sector with promising applications during the ongoing healthcare crises. This critical review focus on understanding recent developments in theranostic applications of functionalized magnetic nanoparticles (MNPs). Given the profound global economic and health burden, we discuss the therapeutic impact of functionalized MNPs in acute and chronic diseases like small RNA therapeutics, vascular diseases, neurological disorders, and cancer, as well as for COVID-19 testing. Lastly, we culminate with a futuristic perspective on the scope of this field and provide an insight into the emerging opportunities whose impact is anticipated to disrupt the healthcare industry.

Abstract
MicroRNAs (miRs) belong to a family of short non-coding endogenous RNAs. Their over-expression correlates with various pathologies: for instance, miRNA-155 (miR-155) is over-expressed upon the development of breast cancers. However, the detection of miRs as disease biomarkers suffers from insufficient sensitivity. In the present study, we propose a protocol for a rapid and efficient generation of magnetic nanoprobes able to capture miR-155, with the aim of increasing its concentration. As a nanoprobe precursor, we first synthesized superparamagnetic iron oxide nanoparticles (SPIONs) coated with covalently attached polyethylene glycol carrying a free biotin terminus (PEG-bi). Using streptavidin–biotin interactions, the nanoprobes were formulated by functionalizing the surface of the nanoparticles with the miR sequence (CmiR) complementary to the target miR-155 (TmiR). The two-step formulation was optimized and validated using several analytical techniques, in particular with Size-Exclusion High Performance Liquid Chromatography (SE-HPLC). Finally, the proof of the nanoprobe affinity to TmiR was made by demonstrating the TmiR capture on model solutions, with the estimated ratio of 18 : 22 TmiR : CmiR per nanoprobe. The nanoprobes were confirmed to be stable after incubation in serum. Two-step formulation of magnetic nanoprobes for microRNA capture.![]()

Abstract
Magnetic nanoparticles with hybrid sensing functions are in wide use for bioseparation, sensing, and in vivo imaging. Yet, nonspecific protein adsorption to the particle surface continues to present a technical challenge and diminishes the theoretical protein detection capabilities. Here, a magneto-plasmonic nanoparticle synthesis is developed that minimizes nonspecific protein adsorption. Building on the success of zwitterionic polymers, a highly stable and anergic nanomaterial, magnetic gold nanoparticles with idealized coating (MAGIC) is obtained with significantly lower serum protein adsorption compared to control nanoparticles coated with commonly used polymers (polyethylene glycol, polyethylenimine, or polyallylamine hydrochloride). MAGIC nanoparticles are able to sense specific bladder cancer biomarkers at low levels and in the presence of other proteins. This strategy may find wide spread applications for in vitro and in vivo sensing as well as isolations.

Abstract
Ever since their discovery, microRNAs (miRNAs/miRs) have astonished us by the plethora of processes they regulate, and thus adding another dimension to the gene regulation. They have been implicated in several diseases affecting cardiovascular, neurodegenerative, hepatic, autoimmune and inflammatory functions. A primate specific exonic miRNA, miR-198 has been vastly studied during the past decade, and shown to have a critical role in wound healing. The aberrant expression of miR-198 was first reported in schizophrenia, linking it to neural development. Later, its dysregulation and tumor suppressive role was reported in hepatocellular carcinoma. However, this was just a beginning, and after which there was an explosion of reports linking miR-198 deregulation to cancers and other ailments. The first target to be identified for miR-198 was Cyclin T1 in monocytes affecting HIV1 replication. Depending on the type of cancer, miR-198 has been shown to function either as a tumor suppressor or an oncomir. Interestingly, miR-198 is not only known to regulate multiple targets and pathways, but also is itself regulated by several circular RNAs and long-non-coding RNAs, highlighting a complex regulatory network. This review highlights the currently understood mechanism and regulation of miR-198 in different diseases, and its possible diagnostic and therapeutic potential.

Abstract
MiR-222-3p was found to be upregulated in plasma of patients with severe preeclampsia (PE). However, its role in PE progression remains elusive. This study aimed to explore the underlying role and mechanism of miR-222-3p in PE progression. Herein, we verified that miR-222-3p was upregulated and HDAC6 mRNA was downregulated in placentas of PE patients compared with normal pregnant controls as measured by RT-qPCR. And miR-222-3p expression was negatively correlated with HDAC6 mRNA expression in PE patients. HTR8/SVneo trophoblast cells were transfected with miR-222-3p mimic or miR-222-3p inhibitor, and we found that MiR-222-3p overexpression inhibited proliferation, migration, and matrix metalloproteinase (MMP)-2 and MMP-9 levels in HTR-8/SVneo cells, while miR-222-3p silencing showed the opposite results. Online bioinformatics analysis and dual-luciferase reporter assay confirmed that HDAC6 was a target of miR-222-3p. HDAC6 overexpression promoted HTR-8/SVneo cell proliferation and migration, while HDAC6 knockdown suppressed cell proliferation and migration. Moreover, HDAC6 overexpression and Notch1 signaling activation both reversed the inhibitory effects of miR-222-3p on trophoblast cell proliferation and migration. Additionally, treatment with miR-222-3p inhibitor attenuated blood pressure and fetal detrimental changes in PE rats. Collectively, our findings suggested that MiR-222-3p inhibited HDAC6 expression and blocked the Notch1 signaling, thus suppressing trophoblast cell proliferation and migration and attenuating blood pressure and fetal detrimental changes in PE rats, which is expected to become a therapeutic target for PE.

Abstract
Engineering of cellular biomolecules is an emerging landscape presenting creative therapeutic opportunities. Recently, several strategies such as biomimetic materials, drug-releasing scaffolds, stem cells, and dynamic culture systems have been developed to improve specific biological functions, however, have been confounded with fundamental and technical roadblocks. Rapidly emerging investigations on the bioengineering prospects of mammalian ribonucleic acid (RNA) is expected to result in significant biomedical advances. More specifically, the current trend focuses on devising non-coding (nc) RNAs as therapeutic candidates for complex neurological diseases. Given the pleiotropic and regulatory role, ncRNAs such as microRNAs and long non-coding RNAs are deemed as attractive therapeutic candidates. Currently, the list of non-coding RNAs in mammals is evolving, which presents the plethora of hidden possibilities including their scope in biomedicine. Herein, we critically review on the emerging repertoire of ncRNAs in neurological diseases such as Alzheimer’s disease, Parkinson’s disease, neuroinflammation and drug abuse disorders. Importantly, we present the advances in engineering of ncRNAs to improve their biocompatibility and therapeutic feasibility as well as provide key insights into the applications of bioengineered non-coding RNAs that are investigated for neurological diseases.

Abstract
Cancer therapy is a fast-emerging biomedical paradigm that elevates the diagnostic and therapeutic potential of a nanovector for identification, monitoring, targeting, and post-treatment response analysis. Nanovectors of superparamagnetic iron oxide nanoparticles (SPION) are of tremendous significance in cancer therapy because of their inherited high surface area, high reactivity, biocompatibility, superior contrast, and magnetic and photo-inducibility properties. In addition to a brief introduction, we summarize various progressive aspects of nanomagnets pertaining to their production with an emphasis on sustainable biomimetic approaches. Post-synthesis particulate and surface alterations in terms of pharmaco-affinity, liquid accessibility, and biocompatibility to facilitate cancer therapy are highlighted. SPION parameters including particle contrast, core-fusions, surface area, reactivity, photosensitivity, photodynamics, and photothermal properties, which facilitate diverse cancer diagnostics, are discussed. We also elaborate on the concept of magnetism to selectively focus chemotherapeutics on tumors, cell sorting, purification of bioentities, and elimination of toxins. Finally, while addressing the toxicity of nanomaterials, the advent of ultrasmall nanomagnets as a healthier alternative with superior properties and compatible cellular interactions is reviewed. In summary, these discussions spotlight the versatility and integration of multi-tasking nanomagnets and ultrasmall nanomagnets for diverse cancer theragnostics. SPION synthesis with ascribed prominence on sustainable procedures. Particulate species, composition, and surface alteration-enabled theragnostics are highlighted. Inherent properties of SPIONs facilitating cancer diagnostics are elaborated. Magnetism-based “chemotherapeutics,” cell-sorting, and bioentity purification are emphasized. Emergence of ultrasmall SPIONs as a healthier option is summarized.

Abstract
Neuroinflammation mediated by microglia has been identified as vital pathogenesis in Parkinson's disease (PD). This study aimed to investigate the role and potential regulatory mechanism of microRNA-330 in the lipopolysaccharide (LPS)-induced chronic neuroinflammatory model. Primary microglia chronic inflammation model and PD animal model were established by LPS treatment. Bulged microRNA-330 sponges containing six microRNA binding sites were constructed and delivered by plasmid or recombinant adeno-associated virus (rAAV2)/5-green fluorescent protein (GFP) vector. The expression levels of microRNA-330 were assessed by a quantitative real-time polymerase chain reaction. Primary microglia polarization was determined by flow cytometry; meanwhile, dopamine and pro-(anti-)inflammatory cytokines were measured by enzyme-linked immunosorbent assay. Expression levels of GFAP, lba1, inducible nitric oxide synthase (iNOS), Arg1, SHIP1, cytoplasmic, and nuclear factor-κB (NF-κB) were analyzed by Western blot. The behavioral deficit was determined by the rotarod test. The expression of microRNA-330 increased in the first 4 days and reached a plateau subsequently after LPS treatment. The sponges-mediated repression effect on M1 polarization was gradually enhanced with time. Treatment of miR-330 sponges increased the SHIP1 and Arg1 expression, and decreased the translocation of NF-κB and iNOS expression, suggesting the repression of inflammation. In the LPS-induced PD mice, administration of rAAV-sponge-GFP suppressed activation of microglia, downregulated proinflammatory cytokines, resumed the secretion of dopamine, rescued the dopaminergic neurons, and alleviated motor dysfunction. Our results demonstrated that microRNA-330 sponges could sustainably suppress LPS-induced polarization of microglia both in vivo and in vitro probably by negatively regulating NF-κB activity via target SHIP1 in microglia, which might be a promising neuroprotective strategy in neurological diseases, such as PD.

Abstract
Circulating biomarkers such as microRNAs (miRNAs), short noncoding RNA strands, represent prognostic and diagnostic indicators for a variety of physiological disorders making their detection and quantification an attractive approach for minimally invasive early disease diagnosis. However, highly sensitive and selective detection methods are required given the generally low abundance of miRNAs in body fluids together with the presence of large amounts of other potentially interfering biomolecules. Although a variety of miRNA isolation and detection methods have been established in clinics, they usually require trained personnel and often constitute labor-, time- and cost-intensive approaches. During the last years, nanoparticle-based biosensors have received increasing attention due to their superior detection efficiency even in very low concentration regimes. This is based on their unique physicochemical properties in combination with their high surface area that allows for the immobilization of multiple recognition sites resulting in fast and effective recognition of analytes. Among various materials, magnetic nanoparticles have been identified as useful tools for the separation, concentration, and detection of miRNAs. Here, we review state-of-the-art technology with regard to magnetic particle-based miRNA detection from body fluids, critically discussing challenges and future perspective of such biosensors while comparing their handling, sensitivity as well as selectivity against the established miRNA isolation and detection methods.

Abstract
OBJECTIVE Report simple reference structure fabrication and validate the precise localization of subdural micro- and standard electrodes in magnetic resonance imaging (MRI) in phantom experiments. APPROACH Electrode contacts with diameters of 0.3 mm and 4 mm are localized in 1.5 T MRI using reference structures made of silicone and iron oxide nanoparticle doping. The precision of the localization procedure was assessed for several standard MRI sequences and implant orientations in phantom experiments and compared to common clinical localization procedures. MAIN RESULTS A localization precision of 0.41 ± 0.20 mm could be achieved for both electrode diameters compared to 1.46 ± 0.69 mm that was achieved for 4 mm standard electrode contacts localized using a common clinical standard method. The new reference structures are intrinsically bio-compatible, and they can be detected with currently available feature detection software so that a clinical implementation of this technology should be feasible. SIGNIFICANCE Neuropathologies are increasingly diagnosed and treated with subdural electrodes, where the exact localization of the electrode contacts with respect to the patient's cortical anatomy is a prerequisite for the procedure. Post-implantation electrode localization using MRI may be advantageous compared to the common alternative of CT-MRI image co-registration, as it avoids systematic localization errors associated with the co-registration itself, as well as brain shift and implant movement. Additionally, MRI provides superior soft tissue contrast for the identification of brain lesions without exposing the patient to ionizing radiation. Recent studies show that smaller electrodes and high-density electrode grids are ideal for clinical and research purposes, but the localization of these devices in MRI has not been demonstrated.

Abstract
The proposal of gene therapy to tackle cancer development has been instrumental for the development of novel approaches and strategies to fight this disease, but the efficacy of the proposed strategies has still fallen short of delivering the full potential of gene therapy in the clinic. Despite the plethora of gene modulation approaches, e.g., gene silencing, antisense therapy, RNA interference, gene and genome editing, finding a way to efficiently deliver these effectors to the desired cell and tissue has been a challenge. Nanomedicine has put forward several innovative platforms to overcome this obstacle. Most of these platforms rely on the application of nanoscale structures, with particular focus on nanoparticles. Herein, we review the current trends on the use of nanoparticles designed for cancer gene therapy, including inorganic, organic, or biological (e.g., exosomes) variants, in clinical development and their progress towards clinical applications.

Abstract
MicroRNAs are types of small single-stranded endogenous highly conserved non-coding RNAs, which play main regulatory functions in a wide range of cellular and physiological events, such as proliferation, differentiation, neoplastic transformation, and cell regeneration. Recent findings have proved a close association between microRNAs expression and the development of many diseases, indicating the importance of microRNAs as clinical biomarkers and targets for drug discovery. However, due to a number of prominent characteristics like small size, high sequence similarity and low abundance, sensitive and selective identification of microRNAs has rather been a hardship through routine traditional assays, including quantitative polymerase chain reaction, microarrays, and northern blotting analysis. More recently, the soaring progression in nanotechnology and fluorimetric methodologies in combination with nanomaterials have promised microRNAs detection with high sensitivity, efficiency and selectivity, excellent reproducibility and lower cost. Therefore, this review will represent an overview of latest advances in microRNAs detection through nanomaterials-based fluorescent methods, like gold nanoparticles, silver and copper nanoclusters, graphene oxide, and magnetic silicon nanoparticles.
