1. An optical sensor for detecting an analyte of interest in a sample, said optical sensor comprising;

  • a sensing layer containing an indicator agent which can react optically with said analyte, a thin film electroluminescent device comprising a luminescent layer which emits light of a predetermined wavelength, wherein said luminescent layer is optically coupled to said sensing layer, wherein said indicator agent absorbs light energy of said predetermined wavelength and in the presence of at least one analyte of interest generates an optical response which is optically detectable and recognizable as indicating the presence of the analyte of interest, and wherein said thin film electroluminescent device comprises an organic electroluminescent material.
