Black pepper assisted biomimetic synthesis of silver nanoparticles

In this paper, we report biomimetic synthesis of silver nanoparticles using crude black pepper (Piper nigrum) extract at room temperature. X-ray diffraction (XRD) pattern suggests the formation and crystallinity of silver nanoparticles. The average particle size of silver nanoparticles was found in the range of 20–50 nm as confirmed by Transmission electron microscopy (TEM). UV–vis absorption shows a characteristic absorption peak of silver nanoparticles at 410 nm. This synthesis approach is cost effective, eco-friendly and promising for the biosensing and nanoelectronic applications.
