Title:
DIELECTROPHORESIS DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2009/044902
Kind Code:
A1
Abstract:
A dielectrophoresis device for handling (moving, stopping, separating, sorting,
and so forth) a dielectric particle by dielectrophoresis and measuring the dielectrophoretic
force. A dielectric solution (S) is placed in a dielectrophoresis device comprising
a case having a flat top or bottom face, and dielectric target small body (particle)
(P) is put therein. A nonuniform alternating electric field is produced inside
the case. By tilting the case (angle θpitch, or another direction),
rotating the case in a tilted plane (rotational angle θyaw),
or adjusting the voltage and frequency of the alternating electric field, imbalance
or balance between the dielectrophoretic force FDEP acting on the
small body and a force FGsinθpitch attributed to
the gravity and buoyancy is caused. Thus, the small body can be moved or stopped.
The dielectrophoretic force FDEP can also be measured by using the
tilt angle (θpitch) of the dielectrophoresis device when the
small body is still.
