The relationship between Dielectrophoresis and impedance response of dielectric particles immersed in aqueous media
The relationship between Dielectrophoresis and impedance response of dielectric particles immersed in aqueous media
Dielectrophoretic force measurements on isolated 50-µm diameter particles of divinylbenzene (DVB) suspended in aqueous solutions show that force is dependent on relaxation mechanisms present at the particle-liquid interface. Measurements on single particles have been extended to measurements on populations of particles. The impedance of aqueous suspensions of particles contained in a gold-plated electrode test cell has been measured over a range of frequency. Data are presented in the form of Cole-Cole plots. It is shown that the dielectrophoretic response of single particles can be related to the frequency-dependent impedance behavior of suspensions of similar particles.

Abstract
Dielectrophoretic force measurements on isolated 50-µm diameter particles of divinylbenzene (DVB) suspended in aqueous solutions show that force is dependent on relaxation mechanisms present at the particle-liquid interface. Measurements on single particles have been extended to measurements on populations of particles. The impedance of aqueous suspensions of particles contained in a gold-plated electrode test cell has been measured over a range of frequency. Data are presented in the form of Cole-Cole plots. It is shown that the dielectrophoretic response of single particles can be related to the frequency-dependent impedance behavior of suspensions of similar particles.
