Simulasi numerik gaya dielektroforesis pada biopartikel berbentuk bola

Abstract

This paper presents results of simulations of the electric field and dielectrophoretic force on a bioparticel suspended in a host liquid lying between point-plate electrodes. The method of calculation is based on the method of dipole images using the finite-elemen technique. We have investigated the effect of the bioparticle permittivity, and liquid permittivity on the dielectrophoresis spectrum. The results show that the bioparticle permittivity, and liquid permittivity influence to the dielectrophoresis spectrum on  the different frekuensi range and the point-plate electrode configuration is suitable with dielectrophoresis system because the configuration  can produce the  inhomogen electric field.

Keywords: Dielectrophoresis, sphere bioparticle, permittivity, point-plate elecrode
