FAST AND SENSITIVE MEASUREMENT OF BIODATA Russian patent published in 2011 - IPC G01N33/553 G01N27/00 A61B5/145 

FIELD: physics.

SUBSTANCE: proposed device comprises surface of binding with binding centers, sensitive element to detect magnetic particles, appliance to attract magnetic structures comprising, at least, one magnetic particle, to and onto binding surface, appliance to vary order and randomising of arrangement of separate magnetic particles relative to binding centers. Appliance to vary order and randomising allows separation of magnetic particles from binding surface so that 90% of separate magnetic particles of magnetic structure make some 10% of sample volume. Method of measuring bio data consists in attracting magnetic structures to and onto sensor binding surface to vary and randomise arrangement of separate magnetic particles relative to binding centers.

EFFECT: faster detection of labeled molecules in fluid.
