In the SPR sensor cell, the core layer includes a uniform refractive index layer and a graded refractive index layer. The graded refractive index layer is arranged between the uniform refractive index layer and the metal layer. A refractive index of the graded refractive index layer is equal to or more than a refractive index of the uniform refractive index layer, and the refractive index of the graded refractive index layer increases continuously from a surface thereof on a uniform refractive index layer side to the metal layer side in a thickness direction of the graded refractive index layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Surface plasmon resonance sensor cell and surface plasmon resonance sensor","description":"The present invention provides an SPR sensor cell having very excellent detection sensitivity, the SPR sensor cell including: an under-cladding layer; a core layer formed so that at least a part of th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9632027","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
