ABSTRACT:
An apparatus and method for classifying, characterizing, or sorting neutral particles, cells or their parts are disclosed. The apparatus and method are based upon both the positive and negative dielectrophoretic movement of neutral particles, cells, microorganisms or organalles when subjected to a nonuniform electric field generated between two electrodes, the exterior surfaces of which are separated by not more than 900 microns. The apparatus and method are particularly applicable with low conductivity suspensions of living cells or their parts.
