摘要：
For the purpose of low cost and sensitive electrochemical detection of 17β-estradiol (E2), a multi-wall carbon nanotube (MWNT)-Nafion modified electrode was fabricated. The MWNT modified electrode shows enhancement for the anodic peak current of E2 compared with the value obtained using a bare electrode. The anodic peak current measured by square wave voltammetry after 5 min open-circuit accumulation was proportional to the concentration of E2 over the range of 2.5 × 10-7 to 10 × 10-6 M, and a detection limit of 1 × 10-8 M was obtained.
