Title
(EN) QUANTITATIVE MICROFLUIDIC DEVICES
(FR) DISPOSITIFS MICROFLUIDIQUES QUANTITATIFS
Abstract
(EN) Described herein are disposable paper-based assay devices for detection and quantitation of analytes in liquid clinical samples, e.g., blood or urine. The devices may be particularly suitable for use in regions of the world where health care infrastructure is absent. The test devices are versatile in that they can be adapted to detect a variety of analytes. The devices are also easy to use and interpret. Typically, all that is needed to conduct an assay is to apply a drop of sample to the indicated location on the device. The devices are typically colorimetric and readable with the naked eye.
(FR) La présente invention concerne des dispositifs de dosage à base de papier jetables pour la détection et la quantification d'analytes dans des échantillons cliniques liquides, par exemple, du sang ou de l'urine. Les dispositifs peuvent être particulièrement adaptés pour utilisation dans des régions du monde dans lesquelles l'infrastructure sanitaire est absente. Les dispositifs de test sont polyvalents en ce qu'ils peuvent être adaptés pour détecter différents analytes. Les dispositifs sont également faciles à utiliser et interpréter. Typiquement, tout ce qui est nécessaire pour conduire un dosage est l'application d'une goutte d'échantillon à l'emplacement indiqué sur le dispositif. Les dispositifs sont typiquement colorimétriques et lisibles à l'œil nu.
