title: Contactless dielectrophoretic manipulation of biological cells using pulsed magnetic fields.
abstract: Contactless method for manipulation of polar or polarisable micro and nanoscale particles based on the dielectrophoresis force exerted by the induced electric field in high pulsed magnetic field is presented in this study. Finite element method analysis of the magnetic and resulting induced electric fields is carried out. The structure of the magnetic field generator that was based on a controlled frequency spark gap, and the structure of the coil that was used as a load are described. Experimental data showing positive dielectrophoresis on the Jurkat T-lymphoblasts is presented. The study discusses further developments of the technique, its limitations and possible applications.
