On-chip spermatozoa trapping by dielectrophoresis

This paper deals with spermatozoa behavior under the influence of non uniform electric fields. Both bipolar and quadripolar microelectrode structures are used to study spermatozoa trapping by negative or positive dielectrophoresis (DEP). These electrode arrays have proven their efficiency to capture motile cells using the action of the dielectrophoretic force. However, fluid flow may also explain some effects observed during our experiments.
