Definition of dielectrophoresis in US English:



  • The migration of uncharged particles toward the position of maximum field strength in a nonuniform electric field.

    • ‘We demonstrate that electrodeless dielectrophoresis can be used for concentration and patterning of both single-strand and double-strand DNA.’
    • ‘Our observation of trapping of small molecules suggests that dielectrophoretic trapping may be applicable to many small molecules, which has not been observed because of the methods used to study dielectrophoresis to date.’
    • ‘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.’
    • ‘DEP traps can use either negative dielectrophoresis pushing cells away from the electrodes or positive dielectrophoresis pulling cells toward the electrodes.’
    • ‘We assign this trapping to strong dielectrophoresis due to the high electric field and electric field gradient in the pipette tip.’
