Beschreibung
Zusammenfassung:	The present invention relates to an optical sensing element for detection of a narcotic, the optical sensing element comprising a fluorescent sensing compound provided on a substrate, wherein emission of the fluorescent sensing compound is quenched in the presence of the narcotic, and wherein the fluorescent sensing compound is non-polymeric and comprises an electron donor moiety, an electron acceptor moiety and a moiety that influences solubility of the compound in a solvent. Sensing devices incorporating the sensing element and methods of detecting narcotics are also described.
