Abstract
AbstractIn the current study, ZnO nanoparticles (ZnO NPs) were synthesized via green chemistry protocols from the Cenchrus setigerus Vahl plant leaf extracts. For the synthesis of ZnO NPs, about 100 mM zinc sulfate heptahydrate salt (ZnSO4·7H2O) was taken in an aqueous solution along with Cenchrus setigerus Vahl extracts as a reducing and capping agent. The reaction mixture was stirred constantly till the color change was observed. The synthesized ZnO NPs were dried and characterized by UV, FT‐IR, PXRD, SEM, and EDX. From the results, the calculated particle size was about 9.91 nm, with a crystalline nature. In UV–visible it shows characteristics peak at the region of 372 nm, while orthorhombic structure was predicted from their SEM analysis. Using the agar well diffusion method, the antibacterial potentials were determined for the synthesized ZnO NPs at three different concentrations: 500, 700, and 900 µg/mL, against Bacillus subtilis, S. aureus, E. coli, and K. pneumoniae. Similarly, the antibacterial potentials were evaluated for herbal handwash, synthesized from the methanolic extract of Ocimum basilicum and Azadirachta indica. The comparison of ZnO NPs incorporated herbal handwash, and herbal handwash was performed against skin pathogens, which were found more beneficial.
