Abstract

A cCVD method for producing transparent, conducting carbon nanotube (CNT) mats of near complete surface coverage is described. Disk-shaped UMEs using the CNT mats reveal reversible electrochemistry for outer sphere redox species and remarkably low capacitance. CNT mat UMEs can be used for the electrochemical detection of dopamine at micromole concentrations in albumin solution, with no decrease in electrode performance even after extensive use.
