Paper Abstract

This work presents the microfabrication procedures and filtering application of a novel 3-D dielectrophoretic chip that possesses a structure similar to a classical capacitor. It is made up by bonding two stainless steel meshes on the opposite sides of a glass frame which is filled with round silica beads. Double filtration actions that are derived from both mechanical and dielectrophoretic means have been tested with yeast cells and a maximum trapping efficiency of approximately 75% has been achieved with initial concentration of 5×106 cells/ml. This was done at an applied voltage of 200 V and a flow rate of 0.1ml/min.
