Patent

CA 2301077

A multi-layer testing column has a chamber having a longitudinal axis and a first end having a first aperture. A plurality of membrane layers are vertically stacked within the chamber and include at least a plurality of solid-phase substrates each carrying a different anti-analyte. A sample can be placed in the chamber such that specific analytes of the sample are bound to the anti-analytes. A sensor can then be used to receive a signal from the substrates and to generate a corresponding electrical signal.

L'invention concerne une colonne d'analyse multicouche comportant une chambre ayant un axe longitudinal et une première extrémité pourvue d'une première ouverture. Une pluralité de couches membranaires sont empilées verticalement à l'intérieur de la chambre et comprennent au moins une pluralité de substrats en phase solide, chacun d'entre eux portant un anti-analyte différent. Un échantillon peut être disposé dans la chambre de manière que des analytes spécifiques de l'échantillon se lient aux anti-analytes. On utilise alors un détecteur pour recevoir un signal en provenance des substrats et générer un signal électrique correspondant.
