Abstract
Provided is a dielectrophoresis apparatus with which it is possible to handle (move, stop, separate and sort, etc.) a dielectric particle utilizing dielectrophoresis and to measure dielectrophoretic force. The interior of a dielectrophoresis device that includes a case having a flat top or bottom surface is filled with a dielectric solution S and accepts introduction of a small target body (particle) P comprising a dielectric. A non-uniform alternating electric field is formed within the case. By tilting the case (through an angle θor other direction), rotating the case in an inclined plane (through a rotational angle θ) or adjusting the voltage and frequency of the alternating electric field, imbalance or balance is produced between a dielectrophoretic force Fthat acts upon the small body and a force Fsin θascribable to gravity and buoyancy, thereby enabling the small body to be moved and stopped. The dielectrophoretic force Fcan also be measured by using the tilt angle θof the dielectrophoresis device prevailing when the small body has come to rest.
