Abstract

The invention integrates a two-stage dielectrophoretic (DEP) droplet dispensing and distribution system with particulate DEP to create a novel LOC platform capable of manipulating biological cells based on the varied dielectrophoretic signatures that distinguish cells in a population, for example, healthy from diseased cells. The two-stage DEP droplet transport system acts as the backbone of this application, providing the essential dispensing and distribution function, while particulate DEP provides the critical capability to characterize and analyze the heterogeneous biological cell populations routinely encountered in biotechnology and clinical settings.
