Chemiresistors represent a powerful class of chemical sensors that can be readily integrated into any electrical system, can be miniaturized, are readily multiplexed, and take nearly zero-power to operate. One of the greatest limitations to these sensors is a lack of selectivity, which is the electronic equivalent of noise. Interference from large varying background signals, such as humidity, can compromise the sensor signal to a point where there is no useful data. To address this challenge, new ways to integrate molecular constructs into carbon nanotube compositions that produce enhanced selectivity to certain molecules or classes of molecules were investigated to increase the signal to noise level in chemical sensors.
