摘要：
The present study, focus on the green synthesis of silver nanoparticles (AgNPs)using natural biomaterial Bombyx mori silk sericin (SS). The silk sericinacted as a reducing, capping agent for the formation of silver nanoparticles and no other chemicals were used in the work. The formed nanoparticle have been characterized by UV-Visible spectroscopy (UV-Vis), X-ray diffraction (XRD), Fourier transfer infrared (FT-IR) spectroscopy,transmission electron microscope (TEM) and dynamics light scatting(DLS)experiments. The formation of spherical AgNPs was confirmed by UV-Vis absorption spectra by showing peak locations in the wavelength range 422-425 nm. XRD study confirmed the crystalline nature of the synthesized nanoparticles. TheXRD peaks observed at scattering angle (2 theta) values 38.70 degrees, 46.92 degrees and 65.06 degrees could be indexed to the (111), (200), and (220) Bragg's refractions of FCC structure of silver metal.The TEM images revealed spherical shape evolution of AgNPs. The size distributions of AgNPs and stability was confirmed with the zeta potential study.
