The invention provides a composition for use in the detection of an intoxicating drug comprising: (i) a first compound that absorbs UV radiation and generates emitted UV radiation at a wavelength absorbable by said intoxicating drug; and (ii) a second compound that absorbs UV radiation emitted by said intoxicating drug upon absorption by said intoxicating drug of said emitted UV radiation and that emits radiation in the visible spectrum; and methods for detecting an intoxicating drug in a sample comprising irradiating with UV radiation a sample contacted with one or two compounds that absorb UV radiation.
L'invention concerne une composition destinée à être utilisée pour la détection d'un stupéfiant, comprenant: (i) un premier composé qui absorbe le rayonnement ultraviolet et génère un rayonnement ultraviolet émis à une longueur d'onde qui peut être absorbée par ledit stupéfiant; et (ii) un second composé qui absorbe le rayonnement ultraviolet émis par ledit stupéfiant lors de l'absorption dudit rayonnement ultraviolet émis par ledit stupéfiant et qui émet un rayonnement dans le spectre visible. L'invention concerne également des procédés permettant de détecter un stupéfiant dans un prélèvement, consistant à appliquer un rayonnement ultraviolet sur un prélèvement mis en contact avec un ou deux composés qui absorbent le rayonnement ultraviolet.
