    Abstract: The invention provides liquid crystal switching devices, liquid crystal cells made from the switching devices, and electrooptical cells made from the switching devices. The invention further provides methods for changing the orientation of a liquid crystal in a liquid crystal switching device. The liquid crystal switching devices are constructed from a redox-active material supported by a substrate and a liquid crystal having a salt dispersed therein disposed atop the redox-active material.

    Abstract: Methods and compositions for detecting a targeted analyte, such as volatile organic compound (VOCs), are disclosed. Specifically, a cholesteric liquid crystal composition comprising a nematic liquid crystal and a chiral dopant transitions to a liquid crystal blue phase or undergoes other optical changes when in contact with a sample containing the analyte. The phase transition can be readily detected with the naked eye. The disclosed methods and compositions may be used in, for example, dosimeters for detecting analyte (e.g., VOC) exposure. Methods and compositions for producing arrays of liquid crystal thin films are also disclosed. The surface between the microwells in a microwell array is coated with a liquid- crystal-phobic material, such as a fluorinated polymer or a fluorinated silane, creating isolated micowell domains that are preferentially wetted by liquid crystal. Liquid crystal can be added to the microwell domains by simple techniques such as spin coating.

    Abstract: The present invention provides devices and methods for detection of analytes based on measuring the anchoring strength of liquid crystals having distorted geometries. Methods for detecting an analyte in a sample include the steps of: (a) capturing an analyte on a substrate surface wherein the substrate surface defines an easy axis when in contact with a liquid crystal. Substrate surface and liquid crystal are brought into contact and an analyte-dependent departure in the orientation of the liquid crystal from the easy axis of the substrate surface is measured. This departure indicates the presence of the analyte in the sample.
