Supramolecular immobilization of laccase on carbon nanotube electrodes functionalized with methylpyrenylaminomethyl anthraquinone for direct electron reduction of oxygen.

An efficient way of immobilizing and wiring a large amt. of laccase on non-covalently-functionalized multi-walled carbon nanotube (MWCNT) electrodes is reported. 1-(2-Anthraquinonylaminomethyl)pyrene and 1-[bis(2-anthraquinonyl)aminomethyl]pyrene were synthesized and studied for their capability to non-covalently functionalize MWCNT electrodes and immobilize and orientate laccase on the nanostructured electrodes. This led to high-performance biocathodes for oxygen redn. by direct electron transfer with max. current densities of (1±0.2) mA cm-2. The performance of the resulting bioelectrodes could be doubled simply by using the bis-anthraquinone compd. The bioelectrodes show excellent stability over weeks and can thus be envisioned in enzymic biofuel cells. [on SciFinder(R)]
