ABSTRACT:
The invention relates to an optochemical sensor functioning in accordance with the FRET-principle and exhibiting an acceptor (chromophore or luminophore) responsive to an analyte contained in a sample medium as well as a donor (luminophore), characterized in that acceptor and donor are located in separate chemical phases, whereby the phase containing the donor is essentially impermeable to the sample medium or to components of the sample medium affecting the luminescence characteristics of the luminophore. The invention further relates to a method for qualitative and/or quantitative determination of at least one analyte and/or component of a gaseous or liquid measuring medium according to the FRET-principle, characterized by the use of the sensor according to the invention.
