Non-covalent double functionalization of carbon nanotubes with a NADH oxidation Ru(II)-based molecular catalyst and a NAD-dependent glucose dehydrogenase

Chem Commun (Camb). 2014 Oct 11;50(79):11731-4. doi: 10.1039/c4cc04758c.

Abstract

We report the double functionalization of multiwalled carbon nanotube electrodes by two functional pyrene molecules. In combination, an immobilized Ru(II)-based NADH oxidation catalyst and glucose dehydrogenase achieve highly efficient glucose oxidation with low overpotential of -0.10 V and high current densities of 6 mA cm(-2).
