Separation of Micro Engineered Particle Using Dielectrophoresis Technique

The process of manipulation and separation of non-contact particles, which is dielectrophoretic technique, DEP will be described in this paper. This indirect physical contact technique, DEP, focuses on the value of dielectric between its particles and the medium to minimize the problems that occur such as physical and chemical damage to the particles when using the direct physical contact technique. This study was carried out by using polystyrene particles of 1 μm, 4.8 μm and 9.9 μm. The difference of size in this polystyrene particles will determine the change in the pattern the related to the Clausius-Mossotti Factor (CMF) in which the particles will be attracting to the electrodes or repelling from the electrodes. Frequency range selected between 0 to 1.5 MHz The new value of the optimum cross-over frequency will give the more efficient manipulation and separation rates. The force that attracting, PDEP on the y axis and the force that repelling, NDEP on the z axis by the polystyrene particles is observed to see the efficiency and reliability of the process. This separation of polystyrene particles is compared with the separation of the pathogenic bacterial cell particles and blood components in human bodies such as RBC and platelets.
