A Facile plant mediated synthesis of silver nanoparticles using an aqueous leaf extract of Ficus hispida Linn. f. for catalytic, antioxidant and antibacterial applications

An aqueous leaf extract of Ficus hispida Linn. f. mediated silver nanoparticles (Ag NPs) have been prepared for reduction of 4-Nitrophenol, antioxidant and antibacterial activity against gram positive bacteria, Bacillus subtilis and gram negative bacteria, Escherichia coli. The rate of formation of...
