DEVICE FOR INDICATING ANALYTE PRESENCE IN SAMPLE IN QUALITATIVE OR QUANTITATIVE WAY Russian patent published in 2003 - IPC

FIELD: medical engineering. SUBSTANCE: device has means for magnetizing arranged relative to detector means in a position that magnetic field produced by the means for magnetizing is weakened at the magnetized place by at least factor 10 or preferentially by factor 1000 or more at the place the sample is disposed for measuring period. A switch usable for turning off the magnetic field produced by means for magnetizing at the place the sample is present at given time being in particular measuring phase of detector means. EFFECT: low cost and standardized magnetorelaxation analyte detection in vitro and in vivo. 32 cl, 5 dwg
