描述了一种CCVD方法，用于制备几乎完全表面覆盖的透明导电碳纳米管(CNT)垫。使用碳纳米管垫的盘状UME揭示了外层球氧化还原物种的可逆电化学以及非常低的电容。碳纳米管可用于白蛋白溶液中微摩尔浓度的多巴胺的电化学检测，即使在广泛使用后，电极性能也不会下降。
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.
