Preparation and Characterization of Hybrid Fe₃O₄/APTES for Immobilization of GOX

Abstract:

This work aims to obtain hybrid from nanoparticles of Fe₃O₄ modified surface with 3-aminopropyltriethoxysilane (APTES) for their use in the immobilization of glucose oxidase (GOX). The obtained material was characterized by XRD, FTIR, SEM, sedimentation test and magnetic separation. Based on the obtained results it showed that the surface modification with APTES was successfully achieved and that the APTES did not changed the magnetic characteristic neither the structure of Fe₃O₄, indicating that the hybrid material obtained is promising for immobilization of GOX.
