However, challenges related to the SPIONs coating impact their stability and MH heating mechanism, hindering its clinical adoption. This work explores diverse SPIONs coating options - oleic acid (OA), dimercaptosuccinic acid (DMSA), and (3-aminopropyl)triethoxysilane (APTES), to improve SPIONS stability under storage while keeping their heating capacity. OA- and DMSA-coated SPIONs, both negatively charged NPs, exhibited similar behavior in protein corona formation and MH tests. The heating capacity of the three types of SPIONs was maintained after 1 month of storage; however, these values significantly decreased to about 60 % of the initial value after 6 months. APTES-coated SPIONs displayed higher protein corona formation, mainly related to the positively charged surface. Interaction studies with three cell lines (fibroblasts, melanoma, and macrophages) revealed enhanced internalization of APTES-coated SPIONs. Only APTES-coated SPIONs achieved therapeutic temperatures in MH assays, reducing melanoma cell viability significantly. The study underscores the importance of nanoparticle surface modifications and the complexity of factors influencing treatment efficacy.

Standard treatments, including surgery, radiotherapy, and chemotherapy with temozolomide (TMZ), are often limited by the ability of the tumor to circumvent therapeutic effects and by the physiological barriers that restrict drug delivery to the brain parenchyma. Specifically, the blood-brain barrier (BBB) and the blood-brain tumor barrier (BBTB) impede the effective concentration of therapeutic agents within the brain, posing a significant challenge in treating GBM. The primary focus of current research has pivoted towards nanotechnology to address these limitations. Due to their size, surface modifications, and capability to encapsulate drugs, nanocarriers like polymeric, metallic, and lipid nanoparticles have shown potential in enhancing the penetration of anticancer agents across the BBB and BBTB, thus increasing treatment efficacy and minimizing general toxicity. Moreover, lipid-based nanoparticles, such as solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs), offer advantages in drug encapsulation, stability, and controlled release metal nanoparticles, including gold and silver nanoparticles, provide unique properties for imaging and photothermal therapy, potentially augmenting the efficacy of conventional treatments. This review elucidates the mechanisms by which nanocarriers cross the BBB and BBTB, emphasizing the importance of physicochemical properties such as size, charge, and surface functionality. The integration of nanotechnology in GBM treatment highlights the potential for nanoparticles to revolutionize drug delivery systems, overcoming the inherent challenges posed by the BBB and the tumor microenvironment.

Owing to the success of former studies of different group III-V binary nanotubes, this study has been performed by using density functional theory (DFT) with the B3LYP functional and LanL2DZ basis set in Gaussian 09 to explore the impact of transition metals (TMs) Vanadium (V), Niobium (Nb), and Tantalum (Ta) on structural, electrical, thermodynamic, and optical properties of two different variants- armchair and chiral structured GaNNTs (Ga₃₀N₃₀) to understand their comparative behavioral changes. The study reveals that doping GaNNTs with V, Nb, and Ta significantly enhances structural stability, especially when replacing the Ga atom. This improved structural stability suggests the potential for tailoring their electronic and mechanical properties. Again, in the case of Nb doping, replacing the N atom increases surface area and enhances reactivity, indicating its potential application in sensor development. Moreover, IR spectroscopy predicts the possibility of the natural existence of energetic favorability of all dopant-modified nanotubes with distinct vibrational signatures. The electronic properties suggest armchair (3, 3) systems especially, Ga₂₉N₃₀-Nb and Ga₂₉N₃₀- Ta, possess bandgaps suitable for replacing silicon-based electronics. On the other hand, the chiral (5, 3) Ga₃₀N₃₀ systems, exhibit metallic or near-metallic behavior with a bandgap of 0.2–0.4 eV, opening new avenues for material design. Also, the thermodynamic study demonstrates a correlation between Ga-site substitution and increased exothermicity during doping. Furthermore, the armchair (3, 3) Ga₃₀N₃₀ systems exhibit higher structural ordering after doping than the chiral (5, 3) Ga₃₀N₃₀ systems. Additionally, distinct UV-Vis absorption characteristics observed for both armchairs (3, 3) Ga₃₀N₃₀, and Ga₃₀N₂₉-Ta indicate their promising potential for optoelectronic, photodetectors, and photovoltaic applications.

The 15%DSPC selectively delivered mRNA to MZB cells, and the MZB cells subsequently accumulated in splenic follicles, which suggests a concentration of antigen proteins in the follicles. In addition, the delivery of antigen-coding mRNA to MZB cells induced MZB cell-specific major histocompatibility complex class I antigens, which was followed by cytotoxic T lymphocyte responses. Furthermore, with no signs of significant toxicity, 15%DSPC shows an anti-tumor effect that is equal to, or perhaps even better than, mRNA cancer vaccines that target dendritic cells in clinical trials. In summary, the results of this study demonstrate the efficacy of using an LNP formulation to target splenic MZB cells as a cancer vaccine.

The synthesized GQDs were functionalized with folic acid to improve their affinity for folate-positive breast cancer cells, thereby extending their circulation time. Ultimately, these GQDs were loaded with the anticancer agent methotrexate (MTX) to mitigate its adverse effects. Transmission electron microscopy (TEM) and atomic force microscopy confirmed the formation of grapheneol quantum dots with a lateral size of around 2.1 ± 0.2 nm.

The photoluminescence measurements showed that the GQDs exhibited high luminescence with intense blue emission and a quantum yield exceeding 72 %. The Raman, X-ray photoelectron spectroscopy, and FTIR measurements revealed that the folic acid decorated the surface of the GQDs. The hydrodynamic light scattering (DLS) and zeta potential measurements indicated that the lateral size of GQDs increases from 2.1 nm to 10 nm, confirming the attachment of the folic acid to the surface of the GQDs. However, the zeta potential of the GQDs changed from −7.6 meV to −14.3 meV, implying the enhancement of the dispersion stability of the GQDs due to the presence of folic acid on their surfaces.

This review assesses the physicochemical properties of biosilica nanoparticles derived from rice husks as a potential material for colloidosome fabrication, focusing on their potential as advanced drug delivery vehicles.
