Abstract

A new assay for dielectrophoresis, consisting of a platinum wire placed along the axis of symmetry of a hollow metal cylinder, was constructed. The main advantage of this device is that because of the simple axisymmetrical electric field the experimental data can be easily interpreted. Preliminary experimental data for adhesion and fusion of red blood cells are reported. The most interesting observation was that fusion of cell membranes can be induced without applying DC electrical pulses, merely because of the dielectrophoretic effect. A possible explanation of this phenomenon is suggested.
