Linear-polarized light is emitted to a particle chip implanted in the skin with modulating its modulating direction continuously. A surface enhanced Raman scattering light of the biological substance generated on the particle chip. A concentration of the biological substance is calculated based on the received signal. The receiving signal satisfy the following equation:R(t)=Am ·sin(ωt)+D, where R(t): received signal, Am: amplitude, t: time, D: a constant number, and ω: angular speed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for measuring a concentration of a biogenic substance contained in a living body","description":"The object of the present invention is to provide a method for measuring concentration of a biological substance contained in a living body in which deterioration of the accuracy due to the reflected ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8515508","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.
