  • Patent number: 10900905
    Abstract: A needle-shaped body protrudes from a cantilever made of Si. Furthermore, the rear face of the cantilever is coated with aluminum (first metal) having a Fermi level higher than that of Si. The cantilever is dipped into an aqueous silver nitride solution containing the ions of Ag serving as a second metal. The electrons of Si flow out to the aqueous silver nitride solution due to the existence of the aluminum, and Ag nanostructures are precipitated at the tip end of the needle-shaped body. A probe for tip-enhanced Raman scattering in which the Ag nanostructures are fixed to the tip end of the needle-shaped body is manufactured. The sizes and shapes of the Ag nanostructures can be controlled properly by adjusting the concentration of the aqueous silver nitride solution and the time during which the cantilever is dipped into the aqueous silver nitride solution.

  • Patent number: 10829042
    Abstract: An imaging apparatus includes an image sensor and an image processor. The image sensor has at least one type of color filter and a specific filter disposed thereon in a manner corresponding to each pixel on a light receiving surface. The specific filter transmits light in a particular wavelength range in which spectral irradiance of sunlight is lower than that in wavelength ranges adjacent to either side of the particular wavelength range. The image processor detects an emission state of a particular light source based on a signal component of an image signal generated by pixels having the specific filters thereon. The particular light source is different from the sunlight.
