Title (EN) AMELIORATED CROSSTALK IMMUNOASSAY TEST DEVICE FOR DETERMINING A CONCENTRATION OF AN ANALYTE
(FR) DISPOSITIF DE TEST D'IMMUNO-ESSAI DE DIAPHONIE AMÉLIORÉ PERMETTANT LA DÉTERMINATION D'UNE CONCENTRATION D'UN ANALYTE
Abstract:
(EN) The present invention relates to systems that utilize a combination of immunoassay and magnetic immunoassay techniques to detect an analyte within an extended range of specified concentrations. In particular, a device includes a first electrochemical sensor positioned within a conduit adjacent to a second electrochemical sensor and spaced apart from one another at a predetermined distance. The first electrochemical sensor includes an immobilized layer of antibodies. The second electrochemical sensor includes a magnetic field disposed locally around the second electrochemical sensor, and the magnetic field is configured to attract magnetic beads onto a surface of the second electrochemical sensor. The device further includes a scavenging electrode positioned between the first electrochemical sensor and the second electrochemical sensor. The scavenging electrode is configured to prevent crosstalk between the first electrochemical immunosensor and the second electrochemical immunosensor.
(FR) La présente invention concerne des systèmes qui utilisent une combinaison de techniques d'immuno-essai et d'immuno-essai magnétique afin de détecter un analyte dans une plage étendue de concentrations spécifiées. En particulier, l'invention concerne un dispositif comprenant un premier capteur électrochimique positionné à l'intérieur d'un conduit adjacent à un second capteur électrochimique et espacés l'un de l'autre selon une distance prédéterminée. Le premier capteur électrochimique comprend une couche immobilisée d'anticorps. Le second capteur électrochimique comprend un champ magnétique disposé localement autour du second capteur électrochimique et le champ magnétique est conçu pour attirer des billes magnétiques sur une surface du second capteur électrochimique. Le dispositif comprend en outre une électrode de balayage positionnée entre le premier capteur électrochimique et le second capteur électrochimique. L'électrode de balayage est conçue pour empêcher la diaphonie entre le premier immunocapteur électrochimique et le second immunocapteur électrochimique.
