From: Counterflow Dielectrophoresis for Trypanosome Enrichment and Detection in Blood
Enrichment of trypanosomes from infected blood.
Total width of the spiral array is 2.9 mm, electrode width and spacing is 30 μm. (a,b) Micrograph following a separation process, with the RBCs having been pushed away from the electrode array. (c) Parasitized blood on the spiral electrode array. (d) Mouse RBCs are levitated and carried to the outer edges of the spiral. (e) Trypanosomes accumulate in the centre of the spiral and undergo circular translational motion. (f) Trypanosomes are trapped along the electrode edges in the centre of the spiral upon switching the AC voltage from quadrature-phase to an opposing two-phase.
