Sameer Sonkusale:
Integrated CMOS-Nano Sensors
Tufts University

Abstract:
This talk will present recent research activities at Tufts University in the area of single chip sensors for chemical sensing. First, an innovative approach termed “CMOS for Nanoassembly (C4NA)” paradigm is presented which seems to be a practical pathway for heterogeneous integration of multiple nanomaterials on the same platform to realize single chip nanosensors. The approach is based on spatially controlled dielectrophoresis (scDEP), which is a low-cost, maskless, electric-field-based directed assembly. The process utilizes CMOS chips as electroactive functional substrates for scDEP of nanomaterials. We will present some preliminary results in utilizing C4NA approach to assemble single walled carbon nanotubes, DNA-functionalized single walled carbon nanotubes, nanowires and graphene for sensing of volatile organic compounds in the environment with potential for breath-based biomedical diagnostics. Second, the talk will introduce CMOS-based electrode arrays utilizing built-in metal layers of the chip as working electrodes for variety of electrochemical sensor applications.
