A platform capable of seamlessly unifying both optoelectrowetting and optoelectronic tweezers has been developed by Justin Valley and co-workers from the Berkeley Sensor and Actuator Center.
The device requires no lithographically defined microelectrodes as it uses light patterning to define the electrodes, which means that manipulation of droplets and the particles within these droplets can occur anywhere on the device surface. Switching between manipulating droplets to manipulating the particles in those droplets is merely a case of altering an externally applied electric frequency.
