摘要
A method of detecting an analyte by: providing a device having a substrate, an alignment layer on the substrate, and a film having 4-pentyl-4′-cyanobiphenyl on the alignment layer; exposing the film to air suspected of containing the analyte; measuring a change in a physical property of the film in response to exposing the film; measuring the kinetics of the change in the physical property; and correlating the kinetics to the concentration of the analyte, identification of the analyte, or both.
