DETECTION METHODS AND SYSTEMS Russian patent published in 2013 - IPC G01N33/543 G01N27/74 

FIELD: chemistry.

SUBSTANCE: biosensor device has a detecting region which is bounded by a bearing surface and a sensor surface which is different from the bearing surface. The bearing surface contains a reagent in a soluble matrix and an inlet opening for the fluid medium sample in the detecting region. The inlet opening lies away from the reagent on the bearing surface and has a capillary. The fluid medium sample is an aqueous composition. A method of making a biosensor device is disclosed, which involves providing the described structural components. Also disclosed is a method of detecting an analyte in the fluid medium sample, involving feeding said medium into the biosensor device, bringing the medium into contact with the reagent, bringing the mixture of the medium and the reagent into contact with the sensor surface and detecting the reaction between the mixture and the sensor surface.

EFFECT: high rate and reproducibility of analysis.
