Abstract
Provided herein is technology relating to detecting gaseous analytes and particularly, but not exclusively, to devices and methods related to detecting gaseous analytes by monitoring changes in liquid crystals upon exposure to the gaseous analytes.
Claims23
A method for detecting an analyte in a gaseous phase, the method comprising:
- 1) providing a liquid crystal assay device comprising a liquid crystal composition and a surface in a channel;
- 2) exposing the liquid crystal assay device to a sample suspected of comprising an analyte;
- 3) contacting the surface with a liquid crystal;
- and
- 4) interrogating the liquid crystal assay device to detect the analyte,
- wherein a change in a property of the liquid crystal composition in the liquid crystal assay device caused by an interaction of the analyte with the liquid crystal assay device is indicative of the presence of the analyte.
3 more elements
A method for monitoring a subject's exposure to a toxic gas, the method comprising:
- 1) providing to the subject a dosimeter badge comprising a liquid crystal assay device;
- 2) measuring a change in a property of a liquid crystal composition in the liquid crystal assay device caused by an interaction of the toxic gas with the liquid crystal composition;
- and
- 3) reporting an exposure to the toxic gas.
