Silicon nanowires as contact between the cell membrane and CMOS circuits
We describe an innovative approach to sensing bioelectric signals at high space-time resolution with low invasiveness based on growing small Silicon Nano Wires (SiNW) at low-temperature (200 °C). The resulting SiNWs are compatible with ICs, allowing on-site amplification of bioelectric signals. We report our preliminary results showing biocompatibility and neutrality of SiNWs used as seeding substrate for cells in culture.
