Amplified electrochemical hydrogen peroxide reduction based on hemin/G-quadruplex DNAzyme as electrocatalyst at gold particles modified heated copper disk electrode.

本文制备了一种新型直流加热金颗粒修饰铜盘电极（Au-HCuDE）。将血红素/G-四链体辣根过氧化物酶模拟DNA酶（HRP-DNAzyme）自组装于加热电极表面，构建了HRP-DNAzyme/Au-HCuDE电化学生物传感器。通过控制电极表面温度，研究了该平台对过氧化氢（H2O2）电催化还原的显著温度效应。随着电极温度升高，HRP-D...
