Next, the rear surface of the metal film is irradiated with excitation light, plasmon scattered light emitted from the proximity of the mark is detected, and, on the basis of the detected plasmon scattered light, location information for the trap region is obtained. Next, the portion of the rear surface of the metal film that corresponds to the trap region arranged at the detected location is irradiated with excitation light, and fluorescence emitted by a fluorescent substance is detected."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Surface-plasmon enhanced fluorescence measurement method, surface-plasmon enhanced fluorescence measurement device, and analytical chip","description":"First, an analytical chip having a prism, a metal film that includes a trapping region having immobilized on the surface thereof a trapping element for trapping a substance to be analyzed, and a mark ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10495576","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.
