中文摘要：

在薄片上 electroosmotic (EO ) micropump (EOP ) 集成于与一个光设法解决的 potentiometric 传感器(臀部) 相结合的一条 microfluidic 隧道。向正确、左的方向的 EO 流动的运动能清楚地在 microfluidic 隧道被观察。当缓冲区答案通过察觉到的区域时，光电流时间和光电流偏爱电压的特征被获得。结果证明在薄片上 EOP 与的联合一臀部是可行的。

英文摘要：

An on-chip electroosmotic（EO） micropump（EOP） was integrated in a microfluidic channel combined with a light-addressable potentiometric sensor（LAPS）. The movement of EO flow towards right and left directions can be clearly observed in the microfluidic channel. The characteristics of photocurrent-time and photocurrent-bias voltage are obtained when buffer solution passes through the sensing region. The results demonstrate that the combination of an on-chip EOP with an LAPS is feasible.
