PROVIDING DEP MANIPULATION DEVICES AND CONTROLLABLE ELECTROWETTING DEVICES IN THE SAME MICROFLUIDIC APPARATUS

摘要

A microfluidic device is provided comprising a combination of dielectrophoretic (DEP) components each having an outer surface and electrowetting (EW) components each having an electrowetting surface. The DEP components can generate net DEP forces on the outer surfaces of the DEP components to facilitate the movement of micro-objects on the outer surfaces, and the EW components change the wetting properties of the electrowetting surfaces and It can facilitate moving droplets of a liquid medium on the wet surfaces. EW components can be used to separate the first portion of the droplet of the liquid medium from the second portion of the droplet, while the DEP components allow the selected micro-objects to be transferred to the first portion of the droplet before separation of the droplet occurs. It can be used to move to a part.
