The use of particle-impact coulometry in identifying and quantifying nanoparticles tagged (or labelled) with electroactive molecules is demonstrated via the detection of 1,4-nitrothiophenol-tagged silver nanoparticles in aqueous dispersion at potentials more negative than -0.17 V (vs. Ag/AgCl, the reduction potential of nitrothiophenol) via monitoring of particle-electrode collisions.
通过监测粒子与电极的碰撞，展示了在比 -0.17 V（相对于 Ag/AgCl，硝基噻吩的还原电位）更负的电势下，使用粒子冲击库仑法识别和定量标记有电活性分子的纳米粒子（或标签）的方法，该方法通过检测在水溶液中分散的 1,4-硝基噻吩标记的银纳米粒子来实现。
