INDICATOR FOR DETECTING BIOLOGICAL FILMS OF BACTERIA ON MEDICAL INSTRUMENTS (VERSIONS) Russian patent published in 2020 - IPC C12Q1/04 G01N33/50 

FIELD: chemistry.

SUBSTANCE: invention relates to organic chemistry and specifically to an indicator for detecting biological films of bacteria on medical instruments. Indicator has a gel-like structure and contains hydrogen peroxide, a hydrogen peroxide stabilizer, N-cocoalkyl-N,N-dimethylamine oxide, N,N-bis(3-aminopropyl)dodecylamine, a corrosion inhibitor, a complexing agent, a thickener and water, with the following ratio of components, wt%: hydrogen peroxide 3.0–10.0; hydrogen peroxide stabilizer 0.5; N-cocoalkyl-N,N-dimethylamine oxide 1.5; N,N-bis(3-aminopropyl)dodecylamine 0.25; corrosion inhibitor 0.05; complexing agent 0.5; thickener 2.0; water – balance. Invention also relates to a version of an indicator.

EFFECT: obtaining new indicators which enable more reliable detection of bacteria on surfaces of medical instruments by detecting them in a biofilm state.
