Studies on biosynthesis of gold nanoparticles By fusarium oxysporum

Abstract

Gold nanoparticles find applications in medicine, catalysis, electronics, and optics owing to their unique properties. Synthesis of gold nanoparticles by Fusarium oxysporum was studied as one of the efficient and ecofriendly alternatives. The extracellular fungal extract was analyzed for its bioreduction potential. The effects of changes in concentration of the precursor salt on the nanoparticle properties were investigated. The initial concentration of the gold ions influences the size of the nanoparticles. The results suggest the potential of employing biological extracts to synthesize nanoparticles and to control nanoparticle size and morphology.
