Abstract
Official abstract text for this publication.
The application discloses a biosensor system ( 1 ) comprising: a biosensor cartridge ( 30 ), a first biosensor magnet assembly ( 10 ) for generating a magnetic field in the biosensor cartridge comprising two magnetic subunits ( 20 a, 20 b ) each having a core ( 22 a, 22 b ) with a top surface ( 24 ) separated by a gap ( 25 ), and wherein the sensor surface comprised by the biosensor cartridge is arranged above the top surfaces of the cores, wherein the two subunits are adapted to generate a magnetic field between the first subunit and the second subunit with magnetic field lines essentially in parallel to the sensor surface to exert forces at magnetic particles in the cartridge. By employing the system for controlling the movement of magnetic particles in immunoassays, more reliable test results are achieved.
First claim
Opening claim text (preview).
The invention claimed is: 1. A biosensor system, comprising: a biosensor cartridge; a first biosensor magnet assembly for generating a first magnetic field in the biosensor cartridge comprising two magnetic subunits each having a core with a top surface separated by a gap, the core tapering in the direction of the biosensor cartridge and having an incline section inclined by 120° to 150° with reference to the perpendicular of the sensor surface of the biosensor cartridge; and…
