A Magnetic-Controlled Amperometric Biosensor Based on Composite Bio-Particulates Fe3O4 and Nano-Au With The Signal Enhancement by Increasing Loading of Horseradish Peroxidase
A novel amperometric biosensor was developed to determine hydrogen peroxide (H2O2) by Fe3O4/Gold nanoparticles (nano-Au)/Horseradish peroxidase (HRP) bio-particulates modified electrode. Nano-Au was assembled onto the surface of mercapto-functional Fe3O4 nanoparticles via covalent linkages between n...
