Floating electrode optoelectronic tweezers: Light-driven dielectrophoretic droplet manipulation in electrically insulating oil medium

Sungyong Park, Chenlu Pan, Ting-Hsiang Wu, Christoph Kloss, Sheraz Kalim et al.
We report an optical actuation mechanism, floating electrode optoelectronic tweezers (FEOET). FEOET enables light-driven transport of aqueous droplets immersed in electrically insulating oil on a featureless photoconductive glass layer with direct optical images. We demonstrate that a 681 [mu]m de- ... [Appl. Phys. Lett. 92, 151101 (2008)] published Mon Apr 14, 2008.
