Abstract

The newly developed configuration included adopting the photosensitive electrode material TiOPc (titanyl phthalocyanine) to create electrowetting on dielectric (EWOD) mechanism. With this new development, the electric potential on the surface of TiOPc could be on-line real-time changed and defined spatially by illuminating spatially distributed light beam patterns. We tried to control the polarized droplets in our EWOD devices by using different light intensities. The experimental results clearly demonstrated that the relationship of light intensity and electrowetting phenomena can provide us with a feasible platform to construct optofluidic chip with potential autonomous manipulation of samples for point-of-care home medical detection applications.
