  • Title: Efficient direct oxygen reduction by laccases attached and oriented on pyrene-functionalized polypyrrole/carbon nanotube electrodes.
    Author: Lalaoui N, Elouarzaki K, Le Goff A, Holzinger M, Cosnier S.
    Journal: Chem Commun (Camb); 2013 Oct 18; 49(81):9281-3. PubMed ID: 23994955.
    Abstract:
    We report the functionalization of multi-walled carbon nanotube (MWCNT) electrodes by oxidative electropolymerization of pyrrole monomers bearing pyrene and N-hydroxysuccinimide groups. Both polymers were applied to the immobilization and electrical wiring of Trametes versicolor laccase via chemical grafting or non-covalent binding. A "pseudo" host-guest interaction of polymerized pyrene with a hydrophobic cavity of laccase was used for the oriented enzyme immobilization on MWCNT electrodes. The latter leads to higher catalytic current for oxygen reduction (1.85 mA cm(-2)) and higher electroenzymatic stability (50% after one month).
