Abstract
A unique approach was carried out to synthesize and compare the silver nanoparticles using the two novel leaf extracts Ocimum sanctum and Ocimum gratissimum. The reduction of the silver ions to silver nanoparticle was confirmed by the presence of peak at 400 to 420 nm observed in the UV-Visible spectrophotometer. The surface morphology and the elemental composition was analyzed using SEM and EDX respectively. The XRD and FTIR spectrum analysis of silver nanoparticles confirms the crystalline structure of silver nanoparticles and the reduction of silver ions to silver nanoparticles. The synthesized silver nanoparticles were used to study its potential effect as antimicrobial agents and its effect on Vigna radiata seeds. FTIR spectra was taken for seed samples to analyze its potential variation in biological constituents stressed with Ag nanoparticles. The band area calculation, mean ratio of peak intensities was also calculated to study the extent of effect on seed samples.
