Fabrication and Estimation of Au Coated γ-Fe2O3 Nanoparticles for Separation and Purification of Biomolecules

Abstract:

Article Preview

Au coated γ-Fe2O3 nanoparticles were prepared by the changing of surface charge of Au and γ-Fe2O3 nanoparticles with pH. Well Au coated γ-Fe2O3 nanocomposite particles developed in the range between isoelectric point of Au and that of γ-Fe2O3 nanoparticles. Immobilization of glutathione (GSH), crystalline polypeptide containing mercapto group, was successfully performed on the well Au coated γ-Fe2O3 nanocomposite particles. Properties of nanoparticles and GSH immobilized Au/γ-Fe2O3 were characterized by UV-vis, LPA, XRD, and TEM.
