Title (EN) METHOD OF DETERMINING THE PRESENCE AND/OR CONCENTRATION OF SUBSTANCES OF INTEREST IN FLUIDS
(FR) PROCEDE POUR DETERMINER LA PRESENCE ET/OU LA CONCENTRATION DE SUBSTANCES D'INTERET DANS DES LIQUIDES
Abstract: front page image
(EN)Magnetic particles coated with specific antibodies for substances of interest are introduced into a fluid sample. Over time and with agitation, the magnetic particles become attached to the substance of interest within the fluid. The fluid is then introduced to a magnetic field gradient provided between two magnets (1, 5). the resultant change to the magnetic filed between the magnets (1, 5) is determine by a Hall Effect device (3) or a plurality of Hall Effect devices (3). This enables the presence and/or concentration of the substance of interest in the sample to be determined.
(FR)Selon l'invention, des particules magnétiques revêtues d'anticorps spécifiques à des substances d'intérêt, sont introduites dans un échantillon liquide. Au cours du temps et sous l'effet de l'agitation, les particules magnétiques se fixent à la substance d'intérêt dans le liquide. Le liquide est ensuite introduit dans un gradient de champ magnétique entre deux aimants (1, 5). La modification résultante du champ magnétique entre les aimants (1, 5), est déterminée par un ou plusieurs dispositifs à effet de Hall (3). Cela permet de déterminer la présence et/ou la concentration de la substance d'intérêt dans l'échantillon.
