Abstract

We report the ability of a novel source - the aqueous extract of pods of Peltophorum pterocarpum for the synthesis of silver nanoparticles (SNPs). SEM analysis exposes the spherical shape of the nanoparticles and UV-vis spectra show the surface plasmon resonance peak at 407nm. XRD analysis showed the crystalline nature of SNPs. FT-IR spectra show the presence of biomolecules which play a role of reduction of AgNO3 and capping the formed SNPs. A negative zeta potential of-15.8mV endorses the stability and dispersion of SNPs. The antibacterial activity of the SNPs was demonstrated against Escherichia coli and anticoagulant activity was also revealed.
