Fabrication of 2D membrane castellated and straight electrode for dielectrophoresis

Abstract

This paper is presenting two fabrication process of electrodes for the used in artificial kidney. The electrodes were made to compare which will represent the best results. Both electrodes undergoes same fabrications process which represent the novelty in this research. Membranes were fabricated in between the electrodes. Both electrodes were deposited with aluminium. Later both electrodes were tested experimentally to find out the result of particles on which electrode performs better. The experiment was taken for 3 minutes on each frequencies. Frequencies were taken during the positive DEP only which are between 100kHz until 3 MHz. The results shown that castellated electrodes able to cleared the particles much faster than straight electrodes. The faster particles cleared the pathways, which resulting particles moving towards the electrodes, this shows higher electric fields is produced. Higher electric fields shows that less voltage needed. Higher voltage has also been avoided in this research in order to avoid the change of biological nature of cells.
