BIOMEDICAL MATERIAL FOR DIAGNOSING PATHOLOGIES IN BIOLOGICAL TISSUES Russian patent published in 2020 - IPC A61K33/244 A61K47/24 A61K49/00 C09K11/79 C09K11/78 B82Y5/00

Abstract RU 2734957 C1

FIELD: biotechnology.

SUBSTANCE: invention relates to methods for diagnosing pathologies in biological tissues. Disclosed is a biomedical material for diagnosing pathologies in biological tissues, comprising a nanosized upconversion luminophore and an organic additive, wherein as an upconversion phosphor it contains a nanoamorphous complex silicate of rare-earth elements of composition Sr₂Y_6.8YbEr_0.2Si₆O₂₆⋅(8.5–10 wt%), and as an organic additive - silicon dimethylglycerolates of composition (CH₃)₂Si(C₃H₇O₃)₂⋅xC₃H₈O₃, where 0.25 ≤ x ≤ 0.40, (balance to 100 wt%).

EFFECT: disclosed biomedical material provides improved visualization of pathological cells of biological tissue by enhancing luminescence of the red radiation component.
