COMPOSITION FOR INTRODUCING QUANTUM DOTS INTO POLYMER MATRICES OF SENSITIVE ELEMENTS OF A LUMINESCENT SENSOR FOR ANALYZING BIOLOGICAL AQUEOUS AND AQUEOUS-ALCOHOLIC MEDIA AND A METHOD FOR PRODUCTION THEREOF Russian patent published in 2021 - IPC C09K11/54 C09K11/56 C08K3/105 C08K3/30 B82Y15/00 B82Y30/00 B82Y40/00 G01Q60/20 

FIELD: measuring equipment.

SUBSTANCE: invention can be used in making sensitive elements of optical sensors intended for analysis of biological aqueous and water-alcohol media. Composition for introduction into polymer hydrophilic porous matrices contains quantum points in microemulsion. Quantum points include a nucleus based on cadmium selenide and semiconductor shells based on cadmium sulphide and/or zinc sulphide. Microemulsion includes an aqueous phase containing water or a mixture of water with an aliphatic alcohol in ratio of 1:1, a non-polar phase containing a non-polar solvent, and a phase of oxyethylated nonionic surfactant, providing hydrophilization of the surface of quantum dots and selected from oxyethylated castor oil (HRE-40), oxyethylated polysorbate (TWEEN-80) or oxyethylated octadecylamine. Said matrix used is polyvinyl alcohol or polyvinyl acetate.

EFFECT: maintaining quantum luminescence output of obtained sensitive elements of optical sensors.
