| 20110007261 | ANALYTE DETECTION USING LIQUID CRYSTALS - Devices and methods for using changes in the defects in micrometer sized dispersed liquid crystal domains to detect or quantify analytes in a test sample, including endotoxin lipopolysaccharide (LPS), are disclosed. The dispersed liquid crystal microdomains are exposed to the test sample, and any changes in the number of defects in the liquid crystal microdomains are detected by detecting changes in the anchoring configuration of the microdomains. Such changes in anchoring configuration indicate the presence of analyte in the test sample. | 01-13-2011 |
| 20110141431 | DETECTING INTERACTIONS - The present invention relates to a liquid crystal device for detecting interactions between a surface and an analyte. Specifically it provides a device for detecting interactions between a surface and an analyte, said device comprising a first substrate having an active surface supporting one or more first analyte(s), a second substrate, and a liquid crystal disposed on the active surface between the first substrate and second substrate, wherein the liquid crystal has a cross-section of varying thickness, wherein the cross-section of the liquid crystal has a first thickness and second thickness that is different to the first thickness, whereby the interaction between the active surface and the first analyte causes the orientation of the liquid crystal to change at a first critical thickness that is between the first and second thicknesses of the liquid crystal. | 06-16-2011 |
| 20120033173 | MULTIFUNCTIONAL OPTICAL SENSOR - The invention relates to a multifunctional optical sensor, having at least 2 areas which independently react to different input parameters, the sensor comprising a substrate and a polymeric layer comprising polymerized liquid crystal monomers having an ordered morphology, wherein the color, the reflectivity or the birefringence of the sensor changes due to a change of the morphology, wherein said change of the morphology is caused by physical contact with a chemical agent such as a gas or liquid a change of temperature, or passage of time. The invention also relates to a process for the preparation of the sensor and for the use of a film comprising a single substrate, a layer having a cholesteric liquid crystalline structure for application in labels for packaging of perishable goods, food, fine chemicals, bio-medical materials. | 02-09-2012 |
| 20120162596 | Encapsulated Polymer Network Liquid Crystal Material, Device and Applications - Polymer network liquid crystal materials have improved mechanical properties such as rigidity and hardness and substantially improved electro-optical performance. The PNLC material can be manufactured with an emulsion process so as to simplify substantially the manufacturing process. Each LC droplet can be configured with the polymer network extending substantially across the LC droplet, and the polymer network may comprise a material to lower substantially the switching voltage, such as a fluorinated acrylate that may interact with the liquid crystal so as to lower the surface tension of the LC droplet. The PNLC material may comprise an interfacial layer combined with the polymer network so as to decrease substantially the driving voltage. | 06-28-2012 |
