Abstract
Electrochemiluminescence (ECL) is often used for high sensitivity detection. We describe a new approach to collecting the ECL signal, by coupling of the excited state of Ru(bpy)(3) with the surface plasmons in a thin gold film. The energy then radiates into the substrate at a defined angle. Surface plasmon-coupled ECL promises to be useful in chemical and biological assays.
摘要
电化学发光（ECL）常用于高灵敏度检测。我们描述了一种收集ECL信号的新方法，即通过将[Ru(bpy)(3)]²⁺的激发态与薄金膜中的表面等离子体激元耦合。然后，能量以特定角度辐射到基底中。表面等离子体激元耦合的ECL有望在化学和生物分析中发挥作用。
