The present invention provides a poly-gamma-glutamic acid/fluorescent dye complex, which contains no radiopharmaceutical and is harmless to the human body. The use of the poly-gamma-glutamic acid/fluorescent dye complex makes it possible to accurately detect the position of a sentinel lymph node in real time without concerns about radioactive contamination."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical-imaging probe for detecting sentinel lymph nodes which contains a composite of poly-gamma-glutamic acid and an optical-imaging dye","description":"The present invention relates to an optical imaging probe for detecting a sentinel lymph node, which contains a complex of poly-gamma-glutamic acid and an optical imaging dye, and more particularly to","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9623121","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.
