Biofunctionalization of Multiwalled Carbon Nanotubes by Irradiation of Electropolymerized Poly(pyrrole-diazirine) Films.

A photoactivatable poly(pyrrole-diazirine) film was synthesized and electropolymd. as a versatile tool for covalent binding of laccase and glucose oxidase on multiwalled carbon nanotube coatings and Pt, resp. Irradn. of the functionalized nanotubes allowed photochem. grafting of laccase and its subsequent direct elec. wiring, as illustrated by the electrocatalytic redn. of oxygen. Moreover, covalent binding of glucose oxidase as model enzyme, achieved by UV activation of electropolymd. pyrrole-diazirine, allowed a glucose biosensor to be realized. This original method to graft biomols. combines electrochem. and photochem. techniques. The simplicity of this new method allows it to be extended easily to other biol. systems. [on SciFinder(R)]
