SUB NANOPARTICLE BY SHELL-COATED NANOPARTICLE ENHANCEMENT RAMAN SPECTROSCOPY, OR METHOD OF DETECTING RAMAN SCATTERED LIGHT FROM MOLECULAR SPECIES BONDED TO THE SAME
To provide a method of allowing the measuring of a sub nanoparticle, and the spectral change caused by the molecular species bonded to this.SOLUTION: A method of detecting a sub nanoparticle of an atomic number 4-147 by a shell-coated nanoparticle enhancement raman spectroscopy, or a signal coming from a molecular species bonded to this sub nanoparticle is provided. The nanoparticle in the shell-coated nanoparticle is a star-shaped nanoparticle having a protrusion projecting outward, the average size of the shell-coated nanoparticle is 10-50 nm, a laser beam is radiated to the shell-coated nanoparticle, a Raman scattered light is detected as a signal from the sub nanoparticle or the molecular species bonded to this.SELECTED DRAWING: Figure 10
