ANALYSIS METHOD AND DEVICE USING MAGNETIC PARTICLES Russian patent published in 2016 - IPC G01N33/543 

FIELD: medicine.

SUBSTANCE: group of inventions relates to diagnostics. Method of detecting an analyte in sample involves application of device for lateral flow analysis (1) containing zone of addition of sample (2), reaction zone (4) and absorption zone (5), wherein said zone form flow path for said sample. Above device also comprises first and second capture molecules able to bind to analyte, wherein first grip molecule carries first mark, which is not magnetic mark, and second grip molecule is attached to magnetic particle. At least part of the flow path contains micro posts representing ledges, in fact, vertical relative to surface and having height, diameter and distance from each other to allow creation of lateral sample flow in said flow path. Method also involves use of movable magnetic force for movement of said second capture molecules with attached magnetic particle. Group of inventions also relates to lateral flow analysis device and devices for reading analysis result on said device.

EFFECT: group of inventions allows simplifying movement of magnetic particles and improves flow control.
