提出了一种基于钛酸盐纳米管(TNTs)和Nafion复合修饰电极构建灵敏稳定的鲁米诺电化学发光平台的新策略，TNTs含有复合修饰电极，对鲁米诺的电化学发光表现出一定的光催化活性，从而显著增强鲁米诺的发光。这一极其灵敏和稳定的平台允许减少实验中的电化学发光鲁米诺试剂。此外，在低浓度鲁米诺溶液中，我们比较了裸玻碳电极和TNT复合修饰电极检测过氧化氢的性能。结果表明，与玻碳电极相比，该平台对过氧化氢特别敏感。因此，通过与适当的酶反应相结合，该平台将成为许多生物分子的敏感基质。
A new strategy for the construction of a sensitive and stable electrochemiluminescent platform based on titanate nanotubes (TNTs) and Nafion composite modified electrode for luminol is described, TNTs contained composite modified electrodes that showed some photocatalytic activity toward luminol electrochemiluminescence emission, and thus could dramatically enhance luminol light emission. This extremely sensitive and stable platform allowed a decrease of the experiment electrochemiluminescence luminol reagent. In addition, in luminol solution at low concentrations, we compared the capabilities of a bare glassy carbon electrode with the TNT composite modified electrode for hydrogen peroxide detection. The results indicated that compared with glassy carbon electrode this platform was extraordinarily sensitive to hydrogen peroxide. Therefore, by combining with an appropriate enzymatic reaction, this platform would be a sensitive matrix for many biomolecules.
