Scheme 2.

Scheme 2.

a) Principles of pDEP attraction and nDEP repulsion of dielectric particles b) Forces acting on a cell in a microfluidic channel. The force of the pDEP attraction toward the electrode tip is balanced by the force of the liquid flowing through the chamber. The dimensions of the capture pocket exclude additional cells to achieve single cell capture.
