The present invention relates to a nanoparticle heterodimer in which Raman-active molecules are located at a binding portion of the nanoparticle heterodimer, and more particularly, to a core-shell nanoparticle heterodimer comprising: a gold or silver core having a surface to which oligonucleotides are bonded; and a gold or silver shell covering the core. In addition, the present invention relates to the core-shell nanoparticle heterodimer, to a method for preparing same, and to the use thereof. L'invention concerne une nanoparticule hétérodimère dans laquelle des molécules actives à effet Raman sont situées au niveau d'une partie de liaison de la nanoparticule hétérodimère, et plus particulièrement, une nanoparticule hétérodimère coeur-écorce comprenant: un noyau d'or ou d'argent possédant une surface à laquelle des oligonucléotides sont liés; et une écorce d'or ou d'argent recouvrant le noyau. En outre, cette invention concerne une nanoparticule hétérodimère coeur-écorce, un procédé destiné à préparer celle-ci, et son utilisation.
