ACTUATION WITH PULSED MAGNETIC FIELD FOR SENSITIVE ANALYSIS Russian patent published in 2014 - IPC G01N33/543 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine, namely to laboratory diagnostics, and may be used to control a magnetic or magnetisable object transfer in a biosensor cartridge. That is ensured by implementing the following stages of: (a) presenting the biosensor cartridge with a laterally extending sensor surface and at least a magnetic field generator to generate a magnetic field with the field gradient perpendicular to the sensor surface; (b) alternately actuating the magnetic field generator so that the generated magnetic field alternately direct the magnetic or magnetisable objects perpendicular to the sensor surface and thereto with pulse lengths of alternative actuation specified so that the above alternative actuation allows for no lateral motion of the magnetisable objects along the lateral direction of the sensor surface and (c) presenting a detection pulse with the magnetic field specified so that to allow for no transfer of the magnetic or magnetisable objects towards the gravity force. There are also presented biosensor systems.

EFFECT: group of inventions provides more sensitive analysis ensured by the gravity force compensation.
