Title:
DEVICE AND METHOD FOR SEPARATING PARTICLES BY DIELECTROPHORESIS
Document Type and Number:
WIPO Patent Application WO2001043880
Kind Code:
A9
Abstract:
The invention relates to a device (1) for continuous separation of a desired fraction of particulate matter from a liquid suspension containing such particulate matter, the device (1) comprising electrode elements (2, 3) and means for generating an alternating non-uniform dielectric field between said electrode elements, wherein a first electrode (2) has the form of a screw conveyor or a helical spiral and is rotatable around its longitudinal axis, and a second electrode (3) is arranged at a distance opposite to the first electrode and has a form other than the rotatable first electrode, and preferably has the form of a tubular housing (3) surrounding the first rotatable electrode (2). The device (1) may be placed inside or outside a container (16) containing a liquid particle suspension. The invention also relates to applications of said device for preparative purposes in the fields of microbiology, biotechnology and medicine, and particularly for the separation of polarizable biological matter such as plant, animal or human cells.
