Abstract: Methods, systems, and devices for manipulating objects are provided. In certain aspects, the methods, systems, and devices can be used for dielectrophoretic manipulation of objects using bipolar electrodes. Some aspects of the methods, systems, and devices of the present disclosure can be used for encapsulation and amplification of samples.

Abstract: Disclosed are microfluidic devices and systems for the desalination of water. The devices and systems can include an electrode configured to generate an electric field gradient in proximity to an intersection formed by the divergence of two microfluidic channels from an inlet channel. Under an applied bias and in the presence of a pressure driven flow of saltwater, the electric field gradient can preferentially direct ions in saltwater into one of the diverging microfluidic channels, while desalted water flows into second diverging channel. Also provided are methods of using the devices and systems described herein to decrease the salinity of water.
