Schematic diagram of the optoelectrofluidic device integrated with a microfluidic channel. Fabrication technique of selectively perforated PDMS microfluidic channel allows the construction of two separated regions for droplet generation and manipulation in a single device.
Fabrication processes for the channel-integrated optoelectrofluidic device. A microchannel was integrated into a hybrid (glass-film) optoelectrofluidic device by selective perforation of PDMS layer to partially expose the photoconductive surface for droplet manipulation.
(a) Captured movie for generation of water droplets at the T-shaped focusing channel with and . Scale bar, . (b) Plot of the water droplet volume according to for different flow rate of water phase.
(a) Captured movie for interactive manipulation—transport and merging—of multiple droplets using an LCD image in the application of voltage of at 100 kHz. (b) Moving velocity of water droplets in hexadecane oil phase according to the applied voltage for different droplet volumes.
