在这项研究中，我们开发了一种微金字塔阵列电极，促进硝酸纤维素膜和电极之间的接触，这是重要的，以实现定量和灵敏的电化学检测系统的免疫色谱。我们使用我们新开发的检测系统评估了micropyamid阵列电极，该系统可以测量膜和电极之间的接触力，并研究了氧化还原电流和接触力之间的关系。通过使用正常脉冲伏安法，我们观察到在与微锥阵列的接触力较低的情况下，平面电极上的还原电流较高。
In this study, we developed a micropyramid array electrode that facilitates contact between a nitrocellulose membrane and electrode, which is important to realize a quantitative and sensitive electrochemical detection system for immunochromatography. We evaluated the micropyamid array electrode with our newly developed detection system that can measure contact forces between a membrane and electrode, and also investigated the relationship between redox current and contact forces. By using normal pulse voltammetry, we observed higher reduction currents over a flat surface electrode at lower contact forces with the micropyramid array.
