One of the most crucial processes in many biomedical applications is the separation of cells and micro-particles from biological fluids3. Water quality analysis to detect viable pathogenic bacterium2, and rare circulating tumour cells (CTCs) isolation from biological samples to detect cancer at its early stage1 are some of the important examples. Dielectrophoresis (DEP), is a technique for sample handling, which employs the electrical signatures of particles in the presence of non uniform electric fields to separate specific cell types4, 5.
