Applicability of copper nodule for biomedical cell capture based on 3D interdigitated microelectrode

This study presents a method to use copper nodules to induce dielectrophoresis force. It can be applied in biomedical cell capture. The capture electrode is a 3D interdigitated microelectrode and also can be used in electrical cell impedance measurement. No additional procedural is needed to form copper nodules. The process is easy, convenient, and the same as a normal 3D electrode manufacture.
