Abstract

In this work, interdigitated arrays of nanowire electrodes are used with one array acting as the working electrode while the other is used to generate the required protons. Finite element simulations of the pH control electrodes were performed to provide insight on the generation and subsequent diffusion of protons. This informed the inter-tine spacing of the electrodes used. This electrochemical pH control method was then used to enable the detection of analytes of interest.

金纳米线的电化学pH控制
在这项工作中,使用了交错排列的纳米线电极,其中一个阵列作为工作电极,而另一个阵列用于产生所需的质子。进行了pH控制电极的有限元模拟,以深入了解质子的产生和随后的扩散。这就决定了所使用电极的时间间隔。然后使用这种电化学pH控制方法来检测感兴趣的分析物。
