The novel approach has been carried for the green synthesis of silver nanoparticles using leaf extract of Cinnamomum tamala and silver nitrate solution. The optimal condition for synthesizing Ag-NPs was obtained by varying the leaf extract concentration, temperature, AgNO3 concentration, effect of ratio of leaf extract to AgNO3 solution,pH and reaction time. The formation of silver nanoparticles was confirmed by UV–Vis spectrophotometer. Fourier transform infrared spectroscopy (FTIR) was used to key out the specific functional groups responsible for the reduction of silver nitrate to form silver nanoparticles and the capping agents present in the leaf extract. Scanning electron microscopy (SEM) represents the morphological characterization of synthesized nanomaterials. Transmission electron microscopy (TEM) analysis revealed that the particles were crystalline, spherical and irregular in shape and the size were 16 nm and 9 nm at 25 °C and 60 °C, respectively. Electron X-ray diffraction (XRD) analysis is used to determine the phase distribution, crystallinity and purity of the synthesized nanoparticles. The synthesized nanoparticles are found to be highly effective against some pathogenic bacteria species, thus signification of the present study is in production of various pharmaceutical and bioactive products.
