Abstract
The biogenic synthesis of ZnO NPs is a promising substitute for the standard method of NP synthesis. In the current study, ZnO nanoparticles were produced biologically. Leaf extract from the Madhuca longifolia (M-ZnO NPs) plant was used to create ZnO NPs, which were then examined using UV-vis, XRD, FTIR, SEM, and TEM. SEM and TEM examination and XRD validated the size and crystalline nature of Zinc oxide nanoparticles, respectively. Functional groups involved in the production of ZnO NPs were visible in the FTIR spectra. By scavenging DPPH free radicals at various concentrations, the antioxidant activity of green ZnO NPs was determined. By using the agar well diffusion method, ZnO NPs were tested for their bactericidal potential against Gram-negative bacteria E. coli and Gram-positive bacteria Staphylococcus aureus bacterial strains. A 96% photodegradation of MB dye and 91% degradation of textile wastewater was observed in green-produced ZnO NPs when exposed to sunshine. The recent work proved that ZnO NPs have substantial antioxidant, antibacterial, and photocatalytic activity. Therefore, the study offers a straightforward, practical, economical, and ecologically secure green synthesis technique for the biofabrication of multifunctional ZnO nanoparticles.
