Amperometric traces (E=0.40 V) recorded at a Pt/GOx/CNT film electrode during the addition of aliquots (1) 0.50 mM H2O2 at 200 s, (2a) 2.0 mM glucose at 200 s, and (2b) 10.0 mM glucose at 250 s. All films contained chitosan as an immobilization matrix. Background electrolyte, air-equilibrated pH 7.40 phosphate buffer (0.050 M).
