Properties and Biomedical Applications of Hydrothermal method Synthesized of Vanadium Oxide nanoparticles

Abstract

Abstract Vanadium oxide thin films were successfully prepared hydrothermally and deposited on a substrate using the drop casting method. Analytical techniques such as XRD, AFM, (SEM) analyses, Ultraviolet-Visible (UV-Vis), PL, and FTIR measurements were used to confirm the characterization of the prepared vanadium oxide NPs. The XRD measurements show that the VO2 thin film was polycrystalline, with a (monoclinic) phase and crystallite size calculated using Scherrer’s equation, as well as dislocation density and microstrain. The optical properties show that the energy gap (4.49) eV, and depending on PL, a single sharp emission peak was found at location 350 nm (3.54 eV). The Antibacterial activity of the vanadium oxide nanoparticles were investigated, with inhibition zone Escherichia coli (17) mm, Staphylococcus aureus 20 mm, Bacillus subtilis 18 mm, and Klebsiella pneumonia 19 mm and Candida isolates 15 mm. The study confirms that the prepared VO2 samples can be used as an antibacterial agent. The results suggest that proper tuning can make them a good antimicrobial agent.
