Liquid crystals formed from molecules weakly tethered to a nanotextured surface could form the basis of highly sensitive, wearable sensors to detect personal exposure to certain synthetic organic chemicals, researchers reported in the August, 17, 2001, issue of the journal Science.
Such sensors could be used to detect environmental exposure to residential pesticides, monitor chemical markers of food spoilage, and could possibly serve some day as sensors for certain toxic nerve gases such as sarin, according to coauthor Nicholas L. Abbott of the University of Wisconsin, Madison.
Techniques to detect such ...
