Abstract:
1. A sample analysis device, comprising: a base body; and multiple nanostructures, which are arranged on the surface of the base body, and each of which has a dielectric body covered with a metal film, wherein the nanostructures form multiple nanostructure lines, and in each nanostructure line, the nanostructures are arranged in a first direction at a first pitch which is smaller than the wavelength of an excitation light, and the nanostructure lines are arranged in a second direction intersecting the first direction at a second pitch which is greater than the first pitch; wherein the second pitch is set to a dimension for establishing a first-order minimum of reflectance at a wavelength shorter than a resonance wavelength of a localized surface Plasmon resonance generated in the metal nanobodies, and further establishing a higher-order minimum than the first-order at a wavelength longer than the resonance wavelength of the localized resonance Plasmon resonance.
