The purpose is to be able to assign, in real time, a specific crossing pathway to a ligand/receptor pair, without the use of molecular labels. The classification is based on changes in the electrical properties of the cells. Various BioMEMS have been designed and fabricated in order to characterize the variation of the electrical properties of the biological cells. We are interested in both dielectric (i.e. polarization) and vibrationnal (i.e. absorption) spectroscopy. Several devices are currently tested for low (<10MHz) and high (>40GHz) frequency range (LFR & HFR) measurements. In the LFR, we have fabricated coplanar and 3D electrodes sensors for impedance measurements. In the HFR, we have designed and processed coplanar waveguides. In the LFR, we have performed static and dynamic measurements on small cluster of cells. In the HFR, we have shown that we can propagate microwaves along submicrometer single wires (Goubau propagation). We are going to use these HFR devices for measurement on small cluster of cells.Show less >
