Abstract
The present disclosure provides multi-walled carbon nanotubes and carbon nanotubes (CNTs) displaying catalytic enzymes bound to the nanotube sidewalls and devices, such as electrodes, incorporating these catalytic enzyme-bound CNTs (cebCNTs).
Claims5
A catalytic electrode formed by:
- (a) attaching a carbon nanotube to the surface of an electrode;
- (b) attaching the linking agent, DDPSE, to the sidewall of the nanotube via a π-π interaction;
- and
- (c) attaching a catalytic enzyme to the DDPSE, wherein the catalytic enzyme is either a multicopper oxidase (MCO) or PQQ-dependent glucose dehydrogenase
- wherein DDPSE is 4,4′-[(8,16-Dihydro-8,16-dioxodibenzo[a,j]perylene-2,10-diyl)dioxy]dibutyric acid di(N-succinimidyl ester).
