摘要：
The biological synthesis of stable silver nanoparticles (SNPs) is reported using Azadirachta indica plant exudate (Neem gum). The SNPs were characterized by means of UV-Visible Spectroscopy, High Resolution Transmission Electron Microscopy and X-ray diffraction. The UV-visible spectra exhibited a sharp peak at 439 nm suggesting the formation of spherical nanoparticles. This was further confirmed by Transmission Electron Micrographs which displayed nanoparticles in the size range of 15-20 nm. The X-ray Diffraction of SNPs synthesized using neem gum exhibited 2θ values assigned to that of silver nano crystals. The SNPs showed anti-microbial activity against E. coli and S. aureus.
