By performing dielectric spectroscopy across a wide spectrum of frequencies (DC-THz), single-cell analysis could be performed without labeling process. That is why we are developing different micro structures, either planar/3D electrodes or transmission lines, and microfluidic devices using BIOMEMS technologies. In our devices, silicon or glass substrates are combined with polymeric materials and gold patterns. For low frequency (LF) applications, PDMS has been chosen while for high frequency (HF) structures, the PPTMDSO is preferred. We are designing the devices thanks to modeling and simulation using either COMSOL (LF) or CST (HF) softwares. Different designs have already been fabricated and are presented in this paper. Finally, we have performed single cell measurements for the low frequency range (<10 MHz) and the next step will focuse on high frequency measurements
