Abstract: The main goal of this project is to develop an ultra-high throughput, ultra-low cost portable chemical sensors. Despite the development chips for these systems, there continues to be a need for improved implementations of micro-scale detection and processing systems for further convenience, scaling and portability. The team propose the development of field effect transistors (FET) based single walled carbon nanotube (SWCNT) sensors for the selective detection of chemicals. They will explore embedding active sensing substrates with electrode structures and electronic detection devices which is one of the biggest challenges for functional integration of complex analytical protocols specially for label-free sensing (ie capacitive, impedance and charge sensors). The ultimate goal of this research is to develop an ultra-high throughput, ultra-low cost portable chemical sensors.

Technology: The creation if a new generations of FET based single walled carbon nanotube (SWCNT) sensors for the selective detection of chemicals.

Significance: The generation of robust FET based sensors with high sensitivity and selectivity to individual anayltes has significant commercial potential with applications in many domains.

Impact: Scalable production of inexpensive FET based chemical sensors can be utilized in multiple sectors that include: Environmental Monitoring, Occupational Safety, Medical Diagnostics, Food and Agriculture.
