Abstract:
The present invention relates a method for producing a non-enzymatic sensor and more particularly a non-enzymatic sensor for detection of uric acid. One of the advantages of the method to present invention is to provide a simplified method for producing a non-enzymatic sensor detecting uric acid which does not require any bio-active substances and thus simplifies the production method. The method reduces the manufacturing costs and can rapidly proceed on a large scale so that the produced electrode is convenient for people to use. Another advantage of the non-enzymatic sensor for detecting uric acid can be reused for a long time.
Abstract:
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.
Abstract:
The present disclosure provides methods and kits to detect and quantitate NOx compounds in a biological sample. The methods include reacting a mixture comprising a nitrite compound a chromogenic reagent to form a colored compound, contacting the mixture with a retention medium configured to retain the colored compound, and detecting the colored compound retained on the retention medium.
Abstract:
Disclosed is a strip for measuring cholesterol data, as well as a method for measuring cholesterol using same. The measuring strip according to one aspect of the present invention comprises: a red blood cell and low density lipoprotein (LDL) cholesterol filtering layer which hemagglutinates red blood cells and deposits low density lipoprotein (LDL) cholesterol at the same time from injected blood to perform red blood cell isolation and low density lipoprotein (LDL) cholesterol isolation at the same time; and a reaction layer which performs a reaction with the blood in which the red blood cells and the low density lipoprotein (LDL) cholesterol are isolated, in order to obtain cholesterol data. The present invention enables red blood cell isolation and low density lipoprotein (LDL) cholesterol isolation to be performed at the same time in a single layer, to thereby reduce the thickness of the strip and the amount of blood required for measurement at the same time.
Abstract:
Described herein are systems and methods for assaying a sample to quantitatively determine the percentage of glycated hemoglobin in the sample.
Abstract:
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.
Abstract:
The invention relates to a test element (110) for detecting at least one analyte in a sample (114), in particular for detecting at least one metabolite in a bodily fluid. The test element (110) comprises at least one test field (116) with a test field surface (124). The test field (116) comprises at least one detection reagent (120) that is adapted to undergo a detectable reaction in the presence of the analyte. The test element (110) further comprises at least one distribution element (126) that has at least one distribution surface (130) facing the test field surface (124). Between the distribution surface (130) and the test field surface (124) is at least one capillary gap (132), wherein the capillary gap (132) is adapted to allow a layer of the sample (114) with a layer thickness of no more than 50 µm to form within the capillary gap (132).
Abstract:
Es wird ein diagnostisches Testelement (110) zum Nachweis eines Analyten in einer Probe (126) einer Körperflüssigkeit, insbesondere in Vollblut, vorgeschlagen. Das diagnostische Testelement (110) umfasst mindestens ein Testfeld (116) mit mindestens einem Nachweisreagens, wobei das Nachweisreagens eingerichtet ist, um bei Anwesenheit des Analyten mindestens eine nachweisbare Veränderung zu durchlaufen, insbesondere eine optische Veränderung. Das Testfeld (116) weist mindestens eine das Nachweisreagens umfassende Nachweisschicht (118) auf, welche Partikel (137) aufweist. Dabei weisen mindestens 90% sämtlicher Partikel (137) der Nachweisschicht (118) eine tatsächliche Partikelgröße von weniger als 10 Mikrometern auf.

Abstract:
A method for manufacturing a test strip is provided. The method comprises selecting a test strip substrate material and positioning the test strip substrate material a predetermined distance from a matrix material disposed on a second substrate, wherein at least one enzyme to be deposited on the test strip substrate and having glucose as an enzymatic substrate is held within the matrix material. A laser pulse is directed towards the matrix material to release at least a portion of the at least one enzyme having glucose as an enzymatic substrate from the matrix material and deposit the enzyme on the test strip substrate.
