Biosynthesis of Titanium Dioxide and Zinc Oxide Nanoparticles from Natural Sources: A Review

摘要

Nanotechnology is one of the ever growing and emerging fields of science. Recently, researchers have shown much interest in the synthesis and utilization of nanoparticles in biological media. Green technology (biosynthesis) is playing a vital role in the synthesis of nanoparticles due to low cost, non-toxicity and other environmental advantages. This review reports the biological synthesis of metal oxide especially titanium dioxide (TiO_2) and zinc oxide (ZnO) nanoparticles using bacterium, fungi, yeast, algae and plant extract.
