A novel non-enzymatic hydrogen peroxide sensor was realized from Mn-nitrilotriacetate acid (Mn-NTA) nanowires, which were successfully fabricated via a facile hydrothermal route. Cyclic voltammetry (CV) revealed that the Mn-NTA nanowires exhibited direct electrocatalytic activity for the oxidation of H(2)O(2) in phosphate buffer solution. The sensor showed linear response to H(2)O(2) at the concentrations range from 5 x 10(-6)M to 2.5 x 10(-3)M with a detection limit of 2 x 10(-7)M. The sensitivity was up to 78.9 microA mM(-1)cm(-2). These results indicated that the Mn-NTA nanowires were promising in realizing non-enzymatic H(2)O(2) detection.
一种新型的非酶过氧化氢传感器是由 Mn-氮三乙酸（Mn-NTA）纳米线实现的，它是通过简单的水热法成功制备的。循环伏安法（CV）表明，Mn-NTA 纳米线在磷酸盐缓冲溶液中对 H（2）O（2）的氧化具有直接电催化活性。该传感器对 H（2）O（2）在 5 x 10（-6）M 至 2.5 x 10（-3）M 的浓度范围内表现出线性响应，检测限为 2 x 10（-7）M。灵敏度高达 78.9 microA mM（-1）cm（-2）。这些结果表明，Mn-NTA 纳米线有望实现非酶过氧化氢检测。
