Abstract

Flerlags blodkultursensor som omfatter et pH-følsomt absorbansfarge- stoff innkapslet i eller isolert av en første, lysgjennomslippende, gassper- meabel, protonugj ennomtrengelig grunnmasse (2) og et pH-ufølsomt fluor- escensfargestoff i en andre grunnmasse (4), hvor åen første og den andre grunnmassen er koblet sammen spektralt, samt fremgangsmåte for anvendelse av sensoren til påvisning av mikroorganis- mer i en blodkulturflaske.Multilayer blood culture sensor comprising a pH-sensitive absorbance dye encapsulated in or isolated by a first, light-permeable, gas-permeable, protonug, impermeable matrix (2) and a pH-insensitive fluorescence dye in a second matrix (4), wherein the first and the second matrix is spectrally coupled, as well as a method for using the sensor to detect microorganisms in a blood culture flask.
