A novel nanomagnet modified with nickel ferrite nanoparticles (NPs) coated hybrid chitosan (Cs-NiFe2O4) was synthesized using the co-precipitation method. The resulting nanomagnets were characterized various techniques. size of nanomagnetic particles estimated to be about 40 nm based on transmission electron microscopy (TEM) image and X-ray diffraction analysis (XRD) pattern (using Debye-Scherrer equation). Scanning (SEM) images indicated that surface Cs-NiFe2O4 NPs is flatter smoother than uncoated NiFe2O4 NPs. According value stream mapping (VSM) analysis, magnetization (17.34 emu/g) significantly lower (40.67 emu/g). higher antibacterial properties Cs. minimum inhibitory concentrations against S. aureus E. coli 128 256 mg/mL, respectively. Antioxidant activity (evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging test) for at concentration 100 µg/mL 35% 42%, Consequently, can proposed as a viable material biomedical applications.

Abstract The indirect dumping of massive volumes toxic dyes into water has seriously affected the ecosystem. Owing to many applications designed nanomaterials in manufacturing process, there is a lot research interest synthesizing using green processes. In this research, byproduct bee was employed synthesize nanoparticles (NPs) ZnO, CuO, and biosynthesized ZnO/CuO (BZC) nanocomposite via utilizing simple approach. To validate effective fabrication BZC nanocomposite, various characterization measurements were applied. FTIR analysis identified functional groups charge producing nanocomposites. Moreover, existence ZnO CuO XRD peaks suggests that nanocomposites successfully biosynthesized. high-resolution XPS spectrum nanocomposite’s Zn2p3, Cu2p3, O1s observed. Our findings indicate successful engineering prepared nanocomposite. For Congo red (CR) fluorescent stain azo dye elimination water, all adsorption parameters examined at room temperature. experiments revealed removal capacity for uptake CR (90.14 mg g −1 ). results show exhibited high capability dye. nanosphere adsorbent offered simple, low-cost, approach purification industrial wastewater control.

Tumor versus Tumor Cell Targeting in Metal-Based Nanoparticles for Cancer Theranostics

International Journal of Molecular Sciences, Год журнала: 2024, Номер 25(10), С. 5213 - 5213

Опубликована: Май 10, 2024

The application of metal-based nanoparticles (mNPs) in cancer therapy and diagnostics (theranostics) has been a hot research topic since the early days nanotechnology, becoming even more relevant recent years. However, clinical translation this technology notably poor, with one main reasons being lack understanding disease conceptual errors design mNPs. Strikingly, throughout reported studies to date on vivo experiments, concepts "tumor targeting" cell are often intertwined, particularly context active targeting. These misconceptions may lead flaws, resulting failed theranostic strategies. In mNPs, tumor targeting can be described as process by which mNPs reach mass (as tissue), while refers specific interaction cells once they have reached tissue. review, we conduct critical analysis key challenges that must addressed for successful either tissue or within Additionally, explore essential features necessary smart where 'smart design' involving advanced consideration physicochemical motifs, physiological barriers overcome and/or
