A nanometer-sized particle comprises a core comprising at least one metal or metal alloy; and a monolayer chemically bonded to the core. The monolayer contains at least one reactive substituent which is coupled to a functional material such that the monolayer is chemically modified. A method of making a functionalized nanometer-sized particle comprises providing a nanometer-sized particle comprising a core which comprises at least one metal or metal alloy, and a monolayer adsorbed onto the core wherein the monolayer includes at least one reactive substituent; and coupling the nanometer-sized particle with a functional material such that the monolayer is chemically modified.

L'invention porte sur une particule de la taille du nanomètre comportant un noyau fait d'au moins un métal et un alliage et une monocouche liée chimiquement au noyau. La monocouche comprend au moins un substituant réactif couplé à un matériau fonctionnel la modifiant chimiquement. L'invention porte également sur un procédé d'obtention d'une particule fonctionnalisée de la taille du nanomètre consistant à prendre une particule de la taille du nanomètre comportant un noyau fait d'au moins un métal et un alliage, et une monocouche adsorbée sur le noyau et comprenant au moins un substituant réactif, et à coupler ladite particule à un matériau fonctionnel modifiant chimiquement la monocouche.
