本研究以焙烧的层状双氢氧化物(CLDH)为修饰电极，探索了一种无酶生物传感器。铜-镁-铝CLDH极大地促进了H_2O_2和GCE之间的电子转移，并在H_2O_2的非酶传感方面得到了应用。结果表明，铜镁铝CLDH具有良好的电催化性能、高灵敏度、良好的重现性、长期稳定性和对H_2O_2还原的快速安培响应，为人工模拟酶在H_2O_2传感器中的应用奠定了基础。这项工作为简单地利用铜-镁-铝共轭脱氢酶作为电子介体来制备高效的过氧化氢生物传感器开辟了一条道路，在未来各种简单、可靠和易于制作的分析方法中显示出巨大的潜在应用前景。(C)2011爱思唯尔B.V.保留所有权利。
An enzymeless biosensor was explored from Cu-Mg-Al calcined layered double hydroxide (CLDH) modified electrode in this study. The Cu-Mg-Al CLDH greatly promotes the electron transfer between H2O2 and GCE, and it is exemplified toward the non-enzymatic sensing of H2O2. The results indicate that the Cu-Mg-Al CLDH exhibits excellent electrocatalytic property, high sensitivity, good reproducibility, long-term stability, and fast amperometric response toward reduction of H2O2, thus is promising for the future development of man-made mimics of enzyme in H2O2 sensors. This work opens a way to utilize simply Cu-Mg-Al CLDH as an electron mediator to fabricate an efficient H2O2 biosensor, which exhibits great potential applications in varieties of simple, robust, and easy-to-make analytical approaches in the future.
