DEVICE FOR APPLICATION AT DETECTING AFFINITY TO BINDING Russian patent published in 2017 - IPC G01N21/77 

FIELD: physics.

SUBSTANCE: device includes a substrate, a planar waveguide located on the substrate, and two optical isolations. The first optical isolation is designed to insert coherent light into the waveguide. The outer surface of the planar waveguide contains binding centres on itself, capable of connecting the specified samples with the binding centres so that field light of damped oscillations is refracted by the specified samples connected with the binding centres. The binding centres are arranged along a plurality of lines placed parallel to one another, with the distance between adjacent straight lines being constant. The lines are placed at an angle relative to the field distribution of damped oscillations so that the coherent light refracted by the specified samples connected with the binding centres falls on the second optical isolation. The second optical isolation outputs the refracted coherent light from the planar waveguide in such a way that it interferes at a predetermined detection location.

EFFECT: increased sensitivity of the device.
