Synthesis of a Range of Functional Oxide and Sulphide Nanoparticles by Biopolymer Stabilization and Enzymatic Treatment

Abstract:

Article Preview

Nanoparticles of the metal oxides magnetite (Fe3O4), cobalt oxide (Co3O4), manganese oxide (Mn3O4) and the metal sulfides CuS, Cu1.96S, Ag2S and CdS were prepared using the biopolymer dextran as a stablising agent. The corresponding enzyme dextranase could then used remove the biopolymer coat to give nanoparticles stabilized by a remnant oligomer. A green and aqueous general route to functional nanoparticles is described.
