| Dielectrophoresis is a phenomenon in which a spatially non-uniform electric field exerts a net force on the field-induced dipole of an uncharged particle. |
| We assign this trapping to strong dielectrophoresis due to the high electric field and electric field gradient in the pipette tip. |
| The observation of flow to the tip during both half cycles is clear indication of an additional flow, which is believed to be due to dielectrophoresis. |
