In recent years, there is significant increase in the attention towards the green synthesis of metal oxide nanoparticles, particularly by the interaction of plant extracts and metal salts; still there is no such published evidence is available on the synthesis of ZnO nanoparticles from aqueous leaf extract of Cotoneaster acuminatus. The synthesis of ZnO nanoparticles was confirmed by using several spectroscopic techniques i.e., UV-Vis, FT-IR, powder-XRD and TEM. It was confirmed from the spectroscopic data that the synthesized nanoparticles were hexagonally orientated, size in the 16-38 nm range and encapsulated by biochemicals present in the leaf extract. These nanoparticles were further evaluated for antimicrobial activity Bacillus subtilisNCFT.583.08, Staphylococcus aureusNCFT.576.08, Pseudomonas aeruginosaNCFT.645.11, Candida albicansNCFT.1006.11 and Saccharomyces cerevisiae NCFT.1008.11strains. This research work might be considered as a successful attempt to create and evaluate medicinal properties of ZnO nanoparticles in combination with Cotoneaster acuminatus leaf extract.
