Abstract A hybrid and straightforward nanosystem that can be used simultaneously for cancer-targeted fluorescence imaging targeted drug delivery in vitro was reported this study. chitosan (CS) polymer coated with reduced graphene oxide (rGO) implanted Fe 3 O 4 nanoparticles fabricated. The fundamental physicochemical properties were confirmed via FT-IR, XRD, FE-SEM, HR-TEM, XPS, VSM analysis. vivo toxicity study zebrafish showed the nanocomposite not toxic. loading amount 0.448 mg/mL −1...
Abstract Green synthesis is one of the rapid, reliable, and best routes for silver nanoparticles (Ag NPs). The current study revealed that aqueous leaf extract Pterocarpus santalinus , which contains steroids, saponins, tannins, phenols, triterpenoids, flavonoids, glycosides, glycerides, found to be responsible bioreduction during spherical Ag nanoparticles. formed NPs were characterized by ultraviolet-visible (UV-vis), Fourier transform-infrared (FT-IR), X-ray diffraction (XRD), atomic...
This work reports an ecofriendly approach for the synthesis of Ruthenium nanoparticles (Ru NPs) using aqueous leaf extract Gloriosa superba. G. superba contains cholidonic, superbine, colchicine, gloriosol, phytosterils and stigmasterin, which are found to be responsible bio-reduction Ru NPs. The synthesized NPs were characterized UV–Vis spectroscopy, Fluorescence spectra, FTIR, XRD, SEM EDX analyses. spectra medium containing showed a gradual decrease absorbance peak observed at 494 nm....
This study reports the synthesis of surface-modified chitosan (CS) coated with reduced graphene oxide/nickel oxide (rGO/NiO) as a multifunctional drug carrier anti-microbial, target-specific, and stimuli-responsive capacities. CS, rGO, NiO nanoparticles are selected due to their pH-responsiveness, large surface area, ROS generating-capacity, respectively. The CS/rGO/NiO nanocomposites (NCs) synthesized using solvothermal approach. Glutaraldehyde is used crosslink CS rGO/NiO enhance stability...
This current work revealed a single-step fabrication of tungsten oxide nanoflakes (WO3 NFs) with the help Terminalia arjuna bark extract. Bioactive phytoconstituents T. extract were involved in nucleation process and promoted material crystalline growth particular direction. The as-prepared sample thermal decomposition was analyzed by TG/DTG. annealed at 300 °C for 2 h, characterized UV-Vis-DRS, FTIR, Raman, XRD, SEM, EDX, TEM. Synthesized WO3 samples showed monoclinic phase flake-like...
Binary metal oxides with carbon nanocomposites have received extensive attention as research hotspots in the electrochemistry field owing to their tunable properties and superior stability. This work illustrates development of a facile sonochemical strategy for synthesis copper bismuthate/graphene (GR) nanocomposite-modified screen-printed electrode (CBO/GR/SPCE) electrochemical detection catechol (CT). The formation an as-prepared CBO/GR nanocomposite was comprehensively characterized....
