Abstract
Provided herein is technology relating to sensors for detecting an analyte and particularly, but not exclusively, to liquid crystal sensors, methods of producing liquid crystal sensors, and methods of using liquid crystal sensors.
Claims10
A method for detecting an analyte, the method comprising:
- 1) providing a liquid crystal sensor comprising:
- a) a liquid crystal;
- b) an alignment functionality that interacts with the liquid crystal;
- and
- c) a detection functionality comprising a metal ion, wherein the alignment functionality is cleavably attached to the detection functionality;
- 2) exposing the liquid crystal sensor to a sample suspected of comprising an analyte, wherein in the presence of the analyte the alignment functionality is cleaved from the detection functionality;
- and
- 3) measuring a detectable property of the liquid crystal, wherein a change in the detectable property of the liquid crystal is indicative of the presence of the analyte.
5 more elements
A method of constructing a liquid crystal sensor, the method comprising:
- a) attaching an anchor functionality to a substrate;
- b) providing a detection functionality that interacts with the anchoring functionality, the detection functionality comprising a metal ion;
- c) cleavably attaching an alignment functionality to the detection functionality;
- and
- d) providing a liquid crystal with which the alignment functionality interacts.
