Functionalization of Magnetite Nanoparticles for Protein Immobilization

Abstract:

Article Preview

The surface of magnetite nanoparticles which have been prepared by coprecipitation method was modified by carboxylic acid group of poly(3-thiophenacetic acid (3TA)). Then the egg white lysozyme was immobilized on the carboxylic acid group of the modification of the magnetite nanoparticles. Lysozyme immobilizing efficiency increased with increasing concentration of 3TA. And the functionalized magnetite particles had higher enzymatic capacity than non-functionalized magnetite nanoparticles.
