A renewable innate source aqueous Capparis decidua stem extract was used to investigate an eco-friendly approach for the synthesis of silver nanoparticles (AgNPs) from silver nitrate solution. Biosynthesized silver nanoparticles were characterized by UV-visible Spectroscopy, Transmission Electron Microscopy (TEM) and Fourier Transform Infra-Red Spectroscopy (FTIR). The UV-visible spectroscopy showed the maximum absorbance i.e. 0.94 at 460 nm. The stability of nanoparticles after four months depicted almost no shift in the absorption intensity and the absorption maxima which indicated that the particle size is same. The broadening of peak specified that the particles were polydispersed. TEM analysis conformed the formation of crystalline silver nanoparticles of size range 1.0-19 nm. Very small size range of silver nanoparticles makes it a good antimicrobial agent. Functional groups like amines, amides, alkynes, alkenes, bromoalkanes etc. identified by FTIR analysis investigated the responsive functional groups which stabilises the synthesized silver nanoparticles. The absorbance bands in bioreduction are observed in the region of 400-4000cm-1 by FTIR.
