Abstract	ZnO nanocrystals have been synthesized by various routes, which are classified by physical, biological & chemical methods. Solution based synthetic methods mainly employ chemicals such as Zinc acetate dehydrate, Zincnitrate, sodium hydroxide, ammonium hydroxide, organic amine set. Although different biological based synthetic methods are known for ZnO nanocrystals are sought by researchers. Biological process has led to the development of an eco-friendly approach for the synthesis of nano particles. The use of non-toxic materials like plant extract & bacteria for synthesis of silver nano particles offers numerous benefits of pharmaceutical application. Synthesis of ZnO nano structures using L-lysine, amino acid and lemon juice have been reported by various researchers. Bio-synthesis of gold nano particles by plant alfalfa have been reported. The development of eco-friendly methods of synthesis of nanoparticles should make an increasing awareness on green chemistry.
