Abstract
The invention provides a device and method for the manipulation of materials (e.g., particles, cells, macromolecules, such as proteins, nucleic acids or other moieties) in a fluid sample. The device comprises a substrate having a plurality of microstructures and an insulator film on the structures. Application of a voltage to the structures induces separation of materials in the sample. The device and method are useful for a wide variety of applications such as dielectrophoresis (DEP) or the separation of a target material from other material in a fluid sample.
