Phytosynthesis and Characterization of Silver Nanoparticles Using Leaf Extracts of Premna Serratiffolia L

Abstract

Biosynthesis of nanoparticles using plants and microbes reduce toxicity and enhance biocompatibility of the particles produced. Phytosynthesis makes use of the principle of reduction of metal ions in aquous extracts of plant leaves that may lead to development of nanoparticles. Therefore, production of silver nanoparticles was experimentally tried out using leaf broth of Premna serratifolia L in accordance with standard procedures. The UV-vis spectra gave an SPR band at 422 nm and TEM analysis revealed the formation of nanoparticles in the range of 3-12 nm. The XRD studies showed that particles are crystalline with face centered cube geometry. The reduction and stabilization of the ions are attributed to the hydroxyl and amine groups present in the leaf broth. This method of synthesis of silver nanoparticles has the potential to become an alternative eco-friendly method of synthesis.
