Liquid Crystal Detection of Volatile Organic Compounds
UW–Madison researchers have developed a novel LC-based method and device for accurately detecting low concentrations of volatile organic compounds.
When exposed to a VOC or other target analyte, blue phase-forming compositions consisting of nematic liquid crystals and chiral dopants undergo a response that can be observed with the naked eye, eliminating the need for additional steps. The VOCs can be detected in gaseous and liquid forms, and the sensitivity of the composition can be adjusted by changing the level of dopant concentration as well as adding non-volatile organics as sensitizing agents.
