We developed a simple, low-cost and novel method for constructing three dimensional (3D) microelectrodes in biomedical devices by utilizing low melting point metal alloy. Three dimensional electrodes have unique properties in biomedical applications such as cell lysis, electroporation, dielectrophoresis, and detection. Compared to other fabrication methods for 3D electrodes, the presented one has many advantages, such as normal experiment conditions, simple processes and low-cost equipments. Numerical analysis on electric potential distribution with different electrode configurations was presented to verify the unique field distribution of arc-shape electrodes fabricated by our method. The application of 3D electrode made by high-conductivity metal alloy microspheres was confirmed by continuous particle sorting based on dielectrophoresis (DEP). The proposed technique offers alternatives to construct 3D electrodes from 2D planer electrodes in microfluidic devices.
