Abstract

In this study, the silver nanoparticles have been green synthesized using C.fenestratum. Synthesized silver nanoparticles have been preliminary validated by the color change to rusty brown from greenish yellow and UV spectroscopy. Morphological analysis through FE-SEM showed cubic and spherical shape of synthesized nanoparticles and the diameter of the synthesized nanoparticles range from 30.18 to 184.89nm.The (EDS) energy-dispersive x-ray spectroscopy spectrum has confirmed the synthesis of AgNPs .The peaks around 400 cm ?1to 600 cm ?1in the IR spectrum indicated the vibration of metals- oxygen (Ag-O), whereas band at 1365.60 cm ?1 and 1357.89 cm ?1 shows the hydroxyl group bending which confirms the synthesis of nanoparticles. The silver nanoparticles exhibited antibacterial activity against E.coli with 20±0.3 mm (Zone of inhibition).
