APPARATUS FOR THE ANALYSIS AND QUANTIFICATION OF THE ANALYTE CONCENTRATION IN A SAMPLE, USING MAGNETORESISTIVE SENSORS

摘要

The invention relates to an apparatus for the analysis and quantification of the analyte concentration in a sample, using external magnetoresistive sensors, comprising: a mechanical system (1), a magnetoresistive sensor (3), and magnetisation means (21 and 22). According to the invention, the mechanical system (1) includes means ensuring that the substrate (4) and the sensor (3) are disposed at the smallest distance possible from one another, so as to obtain a better reading, and the magnetisation means (21 and 22) can take the form of external coils (21), a permanent magnet (22) or a combination of both.
