Synthesis of ZnO Nanoparticles using Lantana camara flower extract

Extremely small nano materials with dimensions roughly less than100 nano meters (nm), can demonstrate atom-like behaviors resulting from higher surface energy because of their large surface area and broad band gap between valence and conduction band when nano materials are divided into near atomic size. ZnO nano powders are basic metal oxide particles with interesting properties and wide applications in several fields. We chose ZnO-NPs as they are promising candidates for various applications such as chemical sensors,nano generators,anti-microbial and anti-corrosive and piezoelectric devices. ZnO nano particles, based on its unique properties such as:low toxicity, high selectivity and biocompatibility, have shown that they are inherently selective cytotoxicity against carcinogenic cells compared with other nanoparticles. Presently the progress of green chemistry in the synthesis of nanoparticles with the use of plants has engrossed a great attention. This study reports the synthesis of ZnO using flower extract of Lantana camara as reducing agent.The study fruitfully reveals simple, fast, economical and eco friendly method of synthesis of multi functional ZnO nanoparticles.
