STRUCTURE, CHIP FOR LOCALIZED SURFACE PLASMON RESONANCE SENSOR, LOCALIZED SURFACE PLASMON RESONANCE SENSOR, AND FABRICATING METHODS THEREFOR

摘要

Implemented is a chip for a localized surface plasmon resonance sensor, which is capable of providing a more highly-sensitive localized surface plasmon resonance sensor. Disclosed is a structure which is provided with a planar section and tubular bodies, wherein the tubular bodies are formed by being erected in such a manner that the openings face the plane of the planar section, the average inner diameter of the openings of the tubular bodies is within a range of 5-2,000 nm inclusive, and the ratio (A/B) of inner diameter (A) of the openings of the tubular bodies to inner diameter (B) in the midpoint of the depth from the openings of the tubular bodies is within a range of 1.00-1.80 inclusive, the bottom sections of the tubular bodies being an aspherical surface.
