Metal nanoparticles have unique properties such as Localized Surface Plasmon Resonance (LSPR). It is known that LSPR can be utilized for Surface Enhanced Raman Spectroscopy (SERS), which needs more sensitivity and stability in future. In our work we proposed a new SERS method, in which nanoparticles arrayed proximally by particle assemblage technology make strong and stable SERS.
