(a) Schematic of (1) the TBAB-modified Nafion polymer-entrapped immobilization, (2) the covalent bonded CNT immobilization and (3) the non-immobilized enzymes. Profiles of voltage versus current density (b) and of power density versus current density (c) using (1) the TBAB-modified Nafion polymer-entrapped immobilization (inserted figure), (2) the covalent bonded immobilization and (3) the non-immobilized enzymes. The experimental conditions were 1 U of G6PDH, 40 U of DI, 10 mM g6p in the 100 mM HEPES (pH 7.5) buffer containing 2 mM NAD+, 10 mM MgCl2 and 0.5 mM MnCl2 at room temperature.
