Green synthesis of copper oxide nanoparticles using aqueous wilayati thulsi (hyptis suveolens) extract- characterization and study of antibacterial effects

The present study deals with the green synthesis and characterization of copper oxide nanoparticles using aqueous leaf extract and their antimicrobial effects on pathogens. The plant extracts plays a vital role in the field of nanotechnology as it is environment friendly and does not involve any harmful chemicals. The current study focused on morphology and size of copper oxide nanoparticles synthesized using Hyptis suaveolens aqueous leaf extract. The synthesized copper oxide nanoparticles were characterized by using UV-Vis spectroscopy, Fourier transform infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM), Energy dispersive X-ray analysis (EDAX) and X-ray diffraction (XRD). Further, as-formed CuO Nps exhibit significant antibacterial activity against pathogenic bacterial strains namely Gram −ve Escherichia coli and Gram +ve bacteria Staphylococcus aureus, Candida albicans. The green synthesized CuO NPs are cost-effective, biogenic molecules with the capability to serve as antimicrobial agents against fish bacterial pathogens.
