Dielectrophoresis can manipulate the movement of particles by controlling the permittivity and conductivity of the particles and medium, and the frequency of the applied alternating electric field, and can isolate and detect specific particles. In order to utilize dielectrophoresis, an electrode capable of forming a non-uniform electric field is important. We fabricated the electrode through photolithography process and used titanium and platinum as electrode material. A chamber filled with a suspension on the electrode was covered to fabricate a device. We observed the particle movement by voltage and frequency using various particles and defined the phenomenon. Finally, a prototype of a dielectrophoretic chip was demonstrated based on the electrode.
