Biosynthesis Of Silver Nanoparticles Using Plant Extract Of Colubrina Asiatica And Its Characterization

Biosynthesis of silver nanoparticles (AgNPs) using plant extract (PE) has gained great interest recently, mainly due to their tremendous availability and various arrays of reducing metabolites. In this study, we investigated the reduction ability of aqueous extract of Colubrina asiatica in order to...
