Chronoamperometry current (μA) versus time (s) plots at the different preparation stages (NFM/CNT + GOX imm; NFM + GOX imm; bare + free GOX; NFM/CNT + free GOX). Comparison with CNT and immobilized and free GOX at day 0. Conditions used: 100 μM ferrocene methanol in 400 mM Britton-Robinson buffer pH 5; +0.5 V applied potential; 1 point/sec; constant 10 μL additions.
