摘要： Described here are patches and methods for measuring glucose in sweat (and tears and the like). In general, the patches comprise an adhesive layer adapted to bond to skin of an individual, a substrate layer disposed over the adhesive layer and comprising a glucose sensing complex including a chromogen that changes color in the presence of certain concentrations of glucose, and a cover. In typical embodiments, the substrate layer has elements formed to direct and accumulate sweat that migrates from the skin of the individual to the glucose sensing complex. Methods of using the invention can comprise cleaning the skin surface, collecting sweat in a patch comprising this microfluidic constellation of elements, and observing concentrations of glucose collected in the sweat, for example either visually, or by using a smartphone or other computer processing device.

摘要： The present invention relates to a strip for an improved lateral flow assay of a biological sample on a single plane and a lateral flow chromatography assay using a test device containing the same. The strip of the present invention consists of a single-pad, which can improve lateral flow assay by providing an easy and simple procedure and clear visual reading. The strip of the present invention is consisted of sample application (sample) zone and reactant-resultant zone where the reaction mixture is deposited (reactant) are all on a same plane. In addition, the present invention provides a chromatographic method wherein hemoglobin is separated from analyte by a differential chromatography on the solid phase. Any interference of detection of the result by hemoglobin is removed by the present invention. The present invention provides advantages including an easy and simple procedure with a quick and clear response.

摘要： Provided are infrared films comprising a substrate, a layer of an aminium radical cation compound in a crystalline state and an organic polymer selected from the group consisting of a divinyl ether polymer, a fluoropolymer, and a silicone polymer, and, optionally, a water repellent layer overlying the layer of the aminium compound. Such infrared films are stable in their optical properties and useful for security markings, test strips for analysis of fluids, and other optical articles for detection in the infrared. Also provided are methods for making such infrared films.

摘要： The present invention is concerned with means and methods for maintaining and preserving enzymatic activity. In particular, the invention relates to a dry composition comprising a dehydrogenase, a redox cofactor, an agent capable of eliciting at least one measurable change in a property of an indicator reagent in the presence of redox equivalents, an indicator reagent, and at least one pyridine-carboxylic acid or a derivative or salt thereof. The invention further contemplates a diagnostic test element for the determination of an analyte from a body fluid sample and a method for the manufacture of such a test element. Further envisaged by the present invention is the use of a pyridine-carboxylic acid or a derivative thereof for reducing a decrease of the enzymatic activity of at least one enzyme in a composition under dry and/or under humid conditions. Furthermore, contemplated is a method for determining the presence or amount analyte in a body fluid sample based on the test element according to the invention.
