Abstract

This research describes an investigation of nonuniform electric field for dielectrophoretic forces, FDEP application in particles manipulation. In an electrokinetics occurrence, a miniaturized array type of two poles microelectrodes has been simulated using engineered particle and tested using graphite metalloid particles. The particles can be attracted towards the regions of strong electric field depending upon the particles is more polarisable than the suspending medium. Dielectrophoresis offers the controllable, selective and accurate manipulation of target graphite metalloid particles. The surface area of graphite attracted to microelectrodes gradually increased starting from 4 seconds for 3412, 3845, and 3764 um2, hence 4589, 4465 and 4739 um2 at the 6 seconds mark and finally 5588, 5569 and 5644 um2 after 8 seconds for three different test run respectively. Further study of optimal FDEP behavior on the electric field distribution for three poles microelectrodes was characterized by finite element method, (FEM). The outcome, FDEP response is further improved by additional poles microelectrodes from top side, instead of side by side in term the strength and direction of electric and displacement field. Ultimately, the findings of this work is possible to contribute in medical sciences research for the enrichment of stem cell from bone narrow and peripheral blood form via integration DEP into a lab on a chip, DLOC concept application.
