摘要

本文介绍了一种利用电解产生的气泡选择性释放颗粒/细胞的方法。粒子/细胞被困在由SU-8制成的微室中，这些微室位于玻璃上的氧化铟锡(ITO)电极的顶部。氧气和氯(或氢)的气泡是通过电极施加电压在靶室中选择性地产生的。我们成功地释放了一个被限制在微室中的微珠(直径100µm)。由于这种方法足够温和，可以维持细胞的活性，我们相信这种方法将用于微阵列细胞的定量分析。

A selective release method using electrolytically generated bubbles for cell array applications

This paper describes a method of selective release of particles/cells by bubbles generated by electrolysis. The particles/cells trapped into microchambers that were produced with SU-8 on the top of an electrode of indium tin oxide (ITO) patterned on glass. The bubbles of oxygen and chlorine (or hydrogen) were selectively generated in a target chamber by applying voltage through the electrodes. We successfully released a microbead (100 µm in diameter) confined in the microchamber. Since this method is gentle enough to maintain the cellular activity, we believe that this method will be useful for quantitative analysis of cells in a microarray.
