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. (C) 2010 Elsevier B.V. All rights reserved.
