Anchored in MIT Department of Chemistry research, C2Sense LLC develops chemiresistive gas sensors for food and agriculture. The technology is a chemiresistive sensor that can detect ethylene, amines and other relevant gases at low parts per million (ppm) and sub-ppm concentrations. The sensors are simple, resulting in low production cost and ease of integration into existing systems and are based on single-walled carbon nanotubes (SWCNTs) that are functionalized with a selector material. Sensors can measure food-freshness markers to help people ship, sell, and consume food before it spoils but can also help protect industrial workers from toxic gases. The firm is addressing digitization of the chemical information via a chemiresistive sensing platform that is simple, inexpensive to implement, and adaptable to nearly all gas-sensing applications.
