Synthesis of Silver Nanoparticles Using Bombyxmori Silk Fibroin and Their Antibacterial Activity
2016
Present work describes the synthesis of colloidal silver nanoparticles using Bombyx mori silk fibroin under white light environment at room temperature. The bio reduction of silver ions showed the unique surface plasmon resonance (SPR) band at 420 nm which was confirmed by UV-visible spectroscopy. Transmission electron microscopy (TEM) showed the synthesized AgNPs are spherical in shape with the average particle size of 35-40 nm. X-ray diffraction (XRD) pattren evidenced the crystalline nature of the AgNPs with FCC structure. The biosynthesized AgNPs showed effective antibacterial activity against bacterial stains Bacillus subtilis, and Salmonella typhi.
