Our Micro-for-Nano (M4N) approach wants to merge the innovative properties of nanomaterials for sensing at nanoscale with the reliability, low-cost and accuracy of CMOS electronics. The Dielectrophoresis (DEP) technique is exploited to assembly different nanosensors onto Multi-Electrode Array (MEA) of the CMOS chip.
The integrated System-on-Chip drives the assembly phase and sensor measurement, if properly configured by an external microcontroller unity. It is also connected to a working-station for real-time data storage, implementing an innovative portable device for nanosensing.
Moreover, our fabrication process of M4N prototypes includes a low-cost Electroless Nickel and Immersion Gold (ENIG) process of the top CMOS microelectrodes.to improve the electric contact with the assembled nanowires.
