BIOSYNTHESIS OF SILVER NANOPARTICLES FROM MORINDA COREIA BUCH.-HAM. AND IT’S ANTIBACTERIAL ACTIVITYAbstract
The synthesis of nanoparticles has become the matter of great interest in recent times due to its various advantageous properties and applications in various fields. Though physical and chemical methods are more popular for nanoparticle synthesis, the biogenic production is a better option due to eco-friendliness. Morinda coreia leaf ethanol extracts was screened for the synthesis of Silver nanoparticle using 0.1mM concentration of silver nitrate. The peak of 482 nm in UV-Vis Spectroscopy confirmed the presence of silver nanoparticle synthesis. Biosynthesized silver nanoparticles characterized by Scanning Electron Microscope (SEM), Fourier Transform Infra Red Spectroscopy (FT-IR) and Energy-dispersive X-ray spectroscopy (EDX). The silver nanoparticles around 90 nm were formed. Biologically synthesized silver nanoparticles were further examined for antimicrobial activity against both Gram-negative and Gram-positive bacteria. It was observed that a clear zone of growth inhibition was against in E. coli, Vibrio cholerae, Staphylococcus aureus, Bacillus sps, Pseudomonas aeruginosa, Klebsiella pneumoniae, Serratia marcescens, Proteus vulgaris, Staphylococcus mutans and Salmonella typhi confirms the antibacterial property of biologically synthesized nanoparticles
