在本篇文章中, 我們提出一個創新的光電鉗子, 它整合了 聚雙甲基矽氧烷的微流晶片和光電鉗子。主要的方法是在 聚雙甲基矽氧烷的表面上使用 金屬網格結構的電極。此電極具有 良好的導電性、透光性，也 可以輕易地與二氧化矽或玻璃材料接合。 成功地展現光操控單一人類細胞Nalm-6於 聚雙甲基矽氧烷的微流通道中。

英文摘要

 

We report on a novel optoelectronic tweezers (OET) that integrates with multilayer PDMS based microfluidic devices for the first time. This is realized by coating the PDMS channels with a Au mesh electrode capable of providing an electrically conductive and optically transparent surface that bonds with an OET surface as well.

Microfluidic integrated OET not only allows continuous delivery of biological samples such as media, cells, and particles into optical manipulation area but also on-chip microfluidic valves for fluid control.
