A method for producing a sensor spot coated with a fluoropolymer-free polymer layer includes coating a substrate with an analyte-sensitive pigment layer arranged on the medium side. The pigment layer contains at least one luminophoric dye and is designed to emit luminescence. The intensity, decay time, or phase shift of the luminescence depends upon the concentration of the analyte. The method also includes coating the pigment layer with a first silicone layer arranged on the medium side, and coating the first silicone layer with a fluoropolymer-free polymer layer that comprises ultra-high molecular weight polyethylene (UHMPE), polyether ether ketone (PEEK), polysulfone (PSU), and polyphenylene sulfide (PPS).
A method for producing a sensor spot coated with a fluoropolymer-free polymer layer, comprising:
A sensor membrane for analyzing an analyte present in a medium, comprising a fluoropolymer-free polymer layer, wherein the fluoropolymer-free polymer layer consists of a polymer or comprises a polymer selected from an ultra-high molecular weight polyethylene (UHMPE), polyether ether ketone (PEEK), polysulfone (PSU), and polyphenylene sulfide (PPS).
A sensor spot coated with a fluoropolymer-free polymer layer and having a convex-shaped surface, facing the medium during operation, for an optical sensor for measuring an analyte in a measuring medium comprising the layers:
A sensor cap for an optochemical sensor for determining and/or monitoring at least one analyte present in a medium, containing:
