Characterization of Silver Nanoparticles Synthesized using Latex of Jatropha curcas and Lannea grandis

This paper reports rapid and eco-friendly biosynthesis of silver nanoparticles using latex of two different plants Jatropha curcas (Jc) and Lannea grandis (Lg). Latex of these plants act as both reducing as well as capping agent. The surface plasmon resonance (SPR) band of as-synthesized silver nanocolloids (AgNC) appeared at 440 nm and 415 nm for the AgNC synthesized by latex of Jc and Lg, respectively. TEM images show that the latex of Lg produced smaller regular-shaped particles than those produced by latex of Jc. The influence of different synthesis parameters like concentration of latex, concentration of metal ion, time of reaction etc., on the morphology of the particles were also studied by monitoring UV-Vis spectra of the samples.
