The invention concerns a composition for marking a solid or liquid product and the method for making such a composition. The method for making a composition for marking solid or liquid products is characterised in that it consists in producing a covalent bond between fluorescent molecules and porous silica microspheres with mineral physical base, for example, by reacting porous silica microspheres having primary amine terminations, with fluorescent molecules having terminations reacting with the primary amines such as a succinimidyl ester termination.
L'invention concerne une composition de marquage d'un produit solide ou liquide et le procédé de fabrication d'une telle composition. Le procédé de fabrication d'une composition de marquage de produits solides ou liquides se caractérise en ce qu'il consiste à créer une liaison covalente entre des molécules fluorescentes et des microsphères à base physique minérale, en faisant par exemple réagir des microsphères de silice poreuse présentant des terminaisons amines primaires, avec des molécules fluorescentes présentant des terminaisons réactives avec les amines primaires telle qu'une terminaison succinimidyl ester.
