Title (EN) DEVICE AND METHOD FOR IMMUNOASSAYS
(FR) DISPOSITIF ET PROCÉDÉ POUR IMMUNOESSAIS
Abstract:
(EN) The present invention relates to a device for carrying out an immunoassay, the device including: a) a substrate; and b) a porous matrix (1) attached onto the substrate, the matrix including: (i) an area for applying a liquid sample (2); (ii) a labeling area (3); and (iii) at least one reaction area (4) that includes an area (5) for displaying the results of the assay and a monitoring area (6), said area for applying the liquid sample (2), said labeling area (3), and said reaction area (4) being in fluid communication. In the monitoring area (6), at least a portion of the porous matrix (1) has pores, the size of which is less than that of the labeled particles, such that at least a portion of the labeled particles from the labeled area (3) is stopped in said monitoring area (6), thus forming a symbol that is visible or observable to a user. The invention also relates to a method for manufacturing the device.
(FR) La présente invention concerne un dispositif pour réaliser un immunoessai le dispositif comprenant : a) un support, b) une matrice poreuse 1, fixée sur le support, la matrice comprenant : (i) une zone d'application d'un échantillon liquide 2, (ii) une zone de marquage 3 et (iii) au moins une zone réactionnelle (4) qui comprend : une zone de visualisation des résultats de l'essai 5 et une zone de contrôle 6, lesdites zones d'application de l'échantillon liquide 2, de marquage 3 et réactionnelle 4 étant en communication de fluide; le dispositif comprenant au niveau de la zone de contrôle 6, au moins une partie de la matrice poreuse 1 présente des pores dont les dimensions sont inférieures à celles des particules marquées, de sorte qu'au moins une partie des particules marquées de la zone de marquage 3 est stoppée au niveau de ladite zone de contrôle 6 formant un symbole qui est visible ou visualisable pour un utilisateur; ainsi qu'un procédé pour fabriquer le dispositif.
