The electron mediator carboxyferrocene was also immobilized on the surface of the GCE. UV-vis spectra, Fourier transform IR spectra, scanning electron microscopy, and electrochemical impedance spectra were acquired to characterize the biosensor. The experimental conditions were studied and optimized. The biosensor responds linearly to H2O2 in the range from 1.0 × 10−5 to 2.0 × 10−3M and with a detection limit of 2.0 × 10−6M (at S/N = 3).
