Title: Dielectrophoresis device and method having insulating ridges for manipulating particles

Patent ·
OSTI ID:936225

Embodiments of the present invention provide methods and devices for manipulating particles using dielectrophoresis. Insulating ridges and valleys are used to generate a spatially non-uniform electrical field. Particles may be concentrated, separated, or captured during bulk fluid flow in a channel having insulating ridges and valleys.
