Biosynthesis of Copper Nanoparticles Using Aqueous Ficus Racemosa Extract- Characterization and Study of Antimicrobial Effects

ABSTRACTDevelopment  of  green  nanotechnology  is  generating  interest  of  researchers  toward  ecofriendly  biosynthesis  of nanoparticles. In  this  study,  biosynthesis  of stable copper  nanoparticles were done using Ficus Racemosa  leaf extract.   First  we  prepared leaf extract of  Ficus Racemosa  sanctum in  deionised water. This  extract added  to  0.02 M of copper sulfate solution and we observed the change in color of the solution from colorless to colored solution, this indicates that there is a formation of Cu nanoparticles.  These biosynthesized  Cu nanoparticles were characterized with the help  of UV –Visible Spectroscopy. It was observed that the Ficus Racemosa  leaf extract can reduce copper ions into copper nanoparticles within 8 to 10 min of reaction time.  Thus, this method can be used for rapid and ecofriendly biosynthesis of stable copper nanoparticles. Further, microscopic examination and antimicrobial activity of synthesized nanoparticles was done against several bacteria and fungi.
