DIFFRACTION-BASED DIAGNOSTIC DEVICE

摘要

FIELD: biology. ^ SUBSTANCE: invention concerns molecular biology and physics and can be applied in detection of analysed object in a medium. Photosensitive layer is formed on a substrate reflecting or diffusing light. This sensitive material is specific to the object to be detected, and can bind it. When the sensitive material covering the substrate is irradiated in the presence of a stencil, a biosensor with a pattern of active and inactive sensitive material areas is obtained. ^ EFFECT: evokes visible diffraction at the contact and light irradiation of a medium containing the analysed object. ^ 23 cl, 5 dwg, 1 ex
