Electric impedance assisted micropipette aspiration.

Micropipette aspiration is a technique to selectively isolate cells from cell cultures using suction pressure. Cells can selectively be isolated one by one from neighboring cells into the micropipette. This paper presents a novel micropipette aspiration system assisted by an impedance measurement system. Furthermore, a method to reduce the adhesion force at a single cell level for a gentler detachment of the cell from a cultivation surface and surrounding cell connections is proposed.
