Rapid biogenic synthesis of silver nanoparticles using black pepper (Piper nigrum) corn extract
Amity Instutute of Applied Science, Amity University, Uttar Pradesh, India.
Rapid biogenic synthesis of silver nanoparticles using extract of black pepper corn was attempted. Aqueous solution of AgNO3 was treated with black pepper corn extract and can reduce most of the silver ions into silver nanoparticles within 120 s of reaction time with the aid of microwave. The formation of nanoparticles is reported by UV-vis spectrophotometer and complemented with characterization using Transmission Electron Microscopy, X-ray Diffraction and Fourier Transform Infrared Spectroscopy. Transmission Electron Microscopy revealed the presence of spherical silver nanoparticles with size ranging of 5 to 50 nm. X-ray diffraction studies corroborated that the biosynthesized nanoparticles are crystalline silver. Furthermore, this green biogenic approach was rapid and simple alternative to chemical synthesis.
