چکیده انگلیسی
The interface behavior and biocatalytic activity of superoxide dismutase (SOD) were studied at carbon nanotube (CNT) surface with cyclic voltammetry (CV). The results show that SOD participates in a rapid exchange with CNT and the process is a single-electron–single-proton process. The electron-transfer coefficient was calculated to be 0.52, the electron-transfer rate constant was 1.4 s−1 and the average surface coverage was measured to be 6.93 × 10−11 ± 4.2 × 10−12 mol cm−2. The bioactive measurements show that SOD keeps its bioactivity at the CNT surface. SOD's remarkable ability to catalyze the dismutation of the superoxide anion (O˙2−) has been demonstrated.
