A three-dimensional hydrogel-modified indium tin oxide electrode with enhanced performance for in situ electrochemical detection of extracellular H 2 O 2
Two different electrochemical sensors (Hemin-G4/Au/GCE and Hemin-G4/Au/ITO) were developed and applied to explore the electrocatalytic capacity of H 2 O 2 reduction. Due to the excellent catalytic activity of Hemin-G4 and high conductivity of gold nanoparticles, both electrodes show excellent electr...
