绝缘微珠和超微电极表面之间碰撞的光学跟踪与电化学测量和 3D 模拟相关。该实验基于珠子对电极表面的部分阻塞。使用这三种方法获得的结果提供了有关着陆位置的径向分布、电流阻塞程度、碰撞频率、碰撞后电极表面上珠子的运动以及碰撞之前和之后在电极表面上的聚集行为的详细信息。
Optical tracking of collisions between insulating microbeads and an ultramicroelectrode surface are correlated to electrochemical measurements and 3D simulations. The experiments are based on partial blocking of the electrode surface by the beads. Results obtained using these three methods provide details regarding the radial distribution of landing locations, the extent of current blockage, collision frequency, motion of beads on the electrode surface following collisions, and aggregation behavior both prior to collisions and afterward on the electrode surface.
