Abstract
ZnO NPs were efficiently synthesized from the leaves extract of Ipomoea pes-caprae. The work focuses on phytochemical studies, phytomediated synthesis and characterization of ZnO NPs and its biological applications. Phytochemicals present in the extract may be responsible for reducing the metal salts into their respective nanosize particles. The UV–Vis spectrum infers the formation of NPs, with absorbed peak at 322 nm. The XRD pattern depicted significant peaks at 2θ positions which confirmed the hexagonal wurtzite structure. FTIR spectrum (ZnO NPs) was recorded to identify the functional group of biomolecules involved in synthesis. ZnO NPs was measured in the range of 2–20 nm by FE-SEM and particle analyses. ZnO NPs in various concentrations revealed potential antioxidant (IC50-21.09) and antibacterial activities. Cytotoxicity activity by Vero cell line (MTT assay) was found to be significant. ZnO NPs exhibited concentration-dependent cytotoxic reactivity to Vero cells after 24-h contact. ZnO NPs exhibited efficient dye degradation of methylene blue in the presence of sunlight. Due to the versatile properties and applications of ZnO NPs, these were widely studied by user-friendly approaches being green, simple and economy.
