## Abstract The voltammetric behaviors of uric acid (UA) and L‐ascorbic acid (L‐AA) were studied at well‐aligned carbon nanotube electrode. Compared to glassy carbon, carbon nanotube electrode catalyzes oxidation of UA and L‐AA, reducing the overpotentials by about 0.028 V and 0.416 V, respectively
