| Abstract | ||||
| Green synthesis of nanoparticles (NPs) has attracted the researcher’s attention, this is because of its rapid, cost-effective, sustainable and eco-friendly nature. The present study reports the successful green synthesis of Zinc oxide nanoparticles (ZnO NPs) using Microtrichia perotitii DC plant leaf extracts as a chelating and capping agent and Zinc Oxide (ZnO) as a precursor. The synthesized nanoparticles were thoroughly characterized using UV-visible spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy and thermogravimetric analysis. X-ray diffraction patterns revealed that ZnO NPs with an average crystallite size of 12.6 nm were synthesized. Scanning electron microscope images show a grain-like nature and with no well-defined morphology. Fourier transform infrared spectrophotometer analysis revealed that the strongest bond at 686 cm-1 corresponds to stretching vibration mode of Zn-O nanoparticles while TGA affirmed the thermal stability of the nanoparticles. The synthesized nanoparticles exhibited antimicrobial activity only against B. subtilis with 25.325 ± 3.51 mm zone of inhibition. | ||||
