Abstract
The present invention aims to provide a chip applied to a molecular sensing device which carries out Raman spectroscopic analysis utilizing Raman scattering enhancement due to plasmons, and that achieves higher sensitivity and stability of its sensing sensitivity and miniaturization, and to provide a molecular sensing device including the chip. As the chip for Raman scattering enhancement applied to the molecular sensing device using the Raman spectroscopic analysis, which has an excitation light source for Raman scattering, a chip for Raman scattering enhancement and a photodetector for observing the Raman scattering, the present invention employs a chip having a molecular detecting element in which a transparent protection material thin filmcomposed of a dielectric material thin film or semiconducting material thin film is formed on a thin filmcontaining the noble metal oxide, and utilizes the Raman scattering enhancement by the thin film containing the noble metal oxide.
