Relocation of individual cells to form patterns based on dielectrophoresis using microdisk electrode with cavity

We present the development of the method for picking up, positioning and relocating single cells based on the di-electrophoresis (DEP). The target cell was captured in the microcavity fabricated on the top of the microdisk electrode by positive DEP (p-DEP). After the trapped cell was transferred to the desired position, negative DEP (n-DEP) was used to release the trapped cell at the desired position. The cell patterns can be formed by the capture and relocation of individual cells with p- and n-DEP.
