Abstract

Nanotechnology, one of the scientific fields and direct most active area of research in all the branches of science. Generally it coalesce the information of chemistry, physics, biology and medicine. Nanotechnology deals productions and stabilizations of various nanoparticles having a size of 1-100 nm in one dimension acting a major role. The need for environmental non-toxic synthetic protocols for nanoparticles synthesis leads to developing interest in biological approaches which are free from the use of toxic chemicals. In this study, simple technique was applied for the synthesis of CuO nanoparticles using carica papaya peel extract. The plant extract acts as reducing, stabilizing and capping agent. Phytochemical test was carried out to identify the compounds responsible for reduction of copper ions. UV-Visible, FTIR and XRD spectral studies were taken to characterize CuO nanoparticles. The prepared nanoparticles was screened for in-vitro antibacterial, antifungal, antioxidant and larvicidal activity.

Keywords: CuO nanoparticles, Carica papaya peel extract, Phytochemicals, Antioxidant, Antimicrobial and larvicidal activity.
