Abstract

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.
