Antimicrobial Activity of Silver Nanoparticles from Pithecellobium Dulce

In this present study, the silver nanoparticles synthesized biologically from the medicinal plant Pithecellobium dulce were tested for its antimicrobial activity against E.coli, S.aureus, P.aeuruginosa, and C.albicans. The biologically synthesized nanoparticles exhibited satisfactory inhibitions against all tested microorganisms when used at different concentrations viz. 1 mM, 3 mM and 5 mM; 3 mM (20 mg/500 μl distilled water) offered the highest sensitivity. Such green-synthesized antibacterial agents locally destroy bacteria, without being toxic to the surrounding tissue.
