Synthesis of silver oxide nanoparticles using aqueous leaf extracts of Viscum orientale Willd, Coleus amboinicus Lour and evaluation of their antibacterial activity

Abstract

The objective of this study was to develop a straightforward biological synthesis of silver oxide nanoparticles (Ag2O NPs) using aqueous leaf extract of Viscum orientale Willd and Coleus amboinicus Lour as a good lowering and capping agent . The UV–visible bands observed at 499 and 451 nm was confirmed the creation of nanosized Ag2O particles making use of Viscum orientale Willd and Coleus amboinicus Lour plants. The formation of Ag2O stretching frequency was confirmed by FTIR spectral studies. Scanning electron microscopy and EDAX analysis displayed Ag2O nanoparticles have been pure and spherical shaped and had been the variety of length from 35±2 nm for (Ag2O NPs) by the usage of Viscum orientale Willd and 32±2 nm for (Ag2O NPs) Coleus amboinicus Lour vice-versa. The fashioned nanoparticles have been cubic in association and face-centered cubic in form, consistent with X-ray diffraction studies. The shaped green kind Ag2O NPs confirmed ambitious antibacterial against each gram possitive and gram negative bacteria.
