Synthesis and use of nanoparticles is a very expanding and a developing area. The development influenced by biological resources for nanoparticles synthesis is emerging into an exciting and the most significant bough of Nanotechnology. Conventionally, chemical reduction is the most frequently applied approach for preparation of metallic nanoparticles but in most of the synthesis protocols it cannot avoid the use of toxic chemicals. Here we report an ecofriendly, cost effective and green approach for synthesis of 1mM AgNO3 solution using the aqueous leaf extracts of Bryophyllum pinnatum (Lam.) as the reducing and capping agent as well. As-synthesized nanoparticles were characterized using UV-VIS spectrophotometer, XRD, FTIR, SEM and TEM. The silver nanoparticles formed were well capped as observed through TEM and showed promising antibacterial activity against E. coli and Staphylococcus aureus.
