Synthesis and Characterization of Copper Nanoparticles by Using a Protein as a Reducer and as Well as a Stabilizer

Synthesis of Copper nanoparticles (CuNPs) by a chemical reduction method is very difficult in aqueous medium than preparation of metallic nanoparticles like Pt, Ag and Au because it (Cu) easily converts into its oxidized form i.e. cupric oxide (CuO). Synthesis of stable CuNPs is described in this present article which is produced by the reaction of few drops hydrazine dihydrate and copper sulfate solution solution followed by catalytic amount of 0.01% b-lg. The whole reaction was carried out in nitrogen environment evolved during this reaction which is a very good advantage of this reaction. Bovine b-lg is utilized here to play dual function of a reducer as well as a stabilizer. Colliodal CuNPs were produced by in this process are characterized by some modern methods like powdered XRD, UV-vis spectroscopy, field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM). One of the main outcome of this present articles is that the synthesis of colloidal CuNPs by a reducer b-lg is not hazardous and environment friendly. This nanoparticles also could be applied in the field of nanomedicines and drug delivery.
