The colloidal silver nanoparticles (AgNPs) were synthesized in situ under white light at room temperature using aqueous silk fibroin (SF) obtained from Bombyxmori silk. The UV-visible spectroscopy revealed the formation of AgNPs by showing a typical surface Plasmon resonance (SPR) band at 422 nm from the UV-visible spectra. The transmission electron microscope (TEM) images show that the formed nanoparticles...
