Preparation of silver nanoparticles using leaf and fruit extracts of Morinda coreia Buck., Ham. –A green approach

Abstract

Nanotechnology has been a recent developed field of science. Several methods were employed to synthesize different types of nanoparticles. In the present study, we demonstrate the synthesis of silver nanomaterials from leaf and fruit aqueous extracts of Morinda coreia Buck., Ham. using the biological method. The silver nanoparticles formation was confirmed by the colour change of the mixture and further confirmed by spectral analysis. The UV-Visible spectrum of colloidal solutions have absorbance peaks at 421.6- 434.4 nm regions with fruit extract and 431.2-442.4 nm regions observed with the leaf extract measured at various time intervals. These nanoparticles were further used to test the antimicrobial activity against five human pathogenic bacteria.
