Magnetic/polymer/nanogold complex using as a novel enzyme support.


A novel enzyme support based on magnetic/polymer/nanogold complex was prepared in this study. At first, carboxymethyl chitosan (CMC) were connected onto the surface of Fe3O4 nanoparticles, and then gold nanoparticles were in situ synthesized and bound to CMC chains, resulting in Fe3O4/CMC/nanogold complex. The complex was determined by UV-vis spectroscopy… (More)
