abstract |
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 dimer, to a method for preparing same, and to the use thereof. |
