Title (EN) MEMBRANE-BASED ANALYTICAL DEVICE FOR BODILY FLUIDS
(FR) DISPOSITIF ANALYTIQUE À MEMBRANE POUR FLUIDES CORPORELS
Abstract:
(EN) The invention relates to an analytical device comprising at least one non-binding membrane; at least one liquid sample application region; and at least one capturing chamber comprising labelled particles; in which device the sample application region(s) are arranged upstream of the membrane while the capturing chamber(s) are arranged downstream of the membrane, and wherein the cut-off of the membrane is large enough to allow passage of labelled particles but small enough to retain clusters comprised of analyte bound to particles. The invention also relates to a method of detecting one or more analytes such as biomarkers in a liquid sample such as blood using a device according to the invention.
(FR) L'invention concerne un dispositif analytique comprenant au moins une membrane sans liaison ; au moins une région d'application d'échantillon liquide ; et au moins une chambre de capture comprenant des particules marquées ; où, dans le dispositif, la ou les région(s) d'application d'échantillon sont agencées en amont de la membrane tandis que la ou les chambre(s) de capture sont agencées en aval de la membrane, et dans lequel le seuil de coupure de la membrane est suffisamment élevée pour permettre le passage de particules marquées mais suffisamment faible pour retenir des agrégats constitués d’analyte lié aux particules. L'invention concerne en outre un procédé de détection d'un ou plusieurs analytes tels que des biomarqueurs dans un échantillon liquide tel que du sang au moyen d'un dispositif selon l'invention.
