Single cell manipulation with dielectrophoresis

Trapping single 15um polystyrene beads in (a) a large 80um diameter trap and (b) 4 independent 40um diameter traps.

Microfluidics and Lab-on-a-chip

We have developed electrodes to immobilise single cells and particles within a microfluidic channel inside a dielectrophoretic trap. The design is highly scalable, and suitable for trapping cells from culture in physiological media. Arrays of these traps have been used to separate mixed populations of fluorescently labelled cells, and these have been recovered and cultured.
