Surfaces coated with a target-induced fluorescent compound are used to detect target elements, especially trace elements. The target-induced fluorescent compound does not fluoresce when excited at a specific wavelength until it has bound a target element. The use of these coated surfaces provides several benefits including reduced background for greater sensitivity and eliminating the need to separate target-induced fluorescent compound that has not bound target element from target-induced fluorescent compound that has bound target element. Coated nanoparticles are especially useful for detection of target elements.
L'invention porte sur des surfaces revêtues de composés à fluorescence induite par une cible, pour la détection d'éléments cibles et spécialement d'éléments à l'état de traces. Lesdits composés ne deviennent fluorescents lorsqu'excités par une longueur d'onde spécifique, qu'au moment où ils se fixent à un élément cible. L'utilisation de ces surfaces revêtues a plusieurs avantages dont un affaiblissement du fond accroissant la sensibilité, et élimine la nécessité de séparer les composés à fluorescence induite par une cible non fixés à un élément cible de ceux fixés à un élément cible. Les nanoparticules revêtues sont spécialement utiles pour la détection d'éléments cibles.
