SYNTHESIS OF GOLD AND SILVER NANO PARTICLES BY PROKARYOTES AND EUKARYOTES A COMPARATIVE STUDY
Wajed Khan* and Pethe A.S.
Silver and gold nano particles are synthesized by prokaryotes as well as eukaryotes. Biosynthetic approach using bacteria and fungus is a novel way towards the development of safe, economically viable and green method for the synthesis of silver and gold nanoparticles and thus synthesized silver and gold nanoparticles can be used in antibacterial formulations. We report the extracellular synthesis of silver and gold nanoparticles using bacteria like pseudomonas and bacillus specie sand fungus like sp.F.solani, Oxysporiu Penicillium, C.lunata, Lindenthianum, Monoliformi,. Detection of synthesized silver and gold nanoparticles was carried out using UV-Visible spectrophotometer analysis, which showed a peak ranging between 420-450 nm indicating the formation of nanoparticles. The method of synthesize of nano particles are ecofreindly easy to synthesized, without any risk and economically viable. In this review article we are comparing the synthesized pattern and way of synthesis of silver and gold nano particles by prokaryotes and eukaryotes differently
Keywords: Fungus, Silver Nanoparticles, gold nano particles, Economically viable.
