A method for sensing a graphene quantum dot includes forming a graphene quantum dot, exciting the graphene quantum dot with light having a first wavelength, measuring light emitted by the excited graphene quantum dot at a second wavelength different from the first wavelength. A graphene quantum dot includes carbon atoms and nitrogen atoms where the nitrogen atoms are present within the graphene quantum dot at a level between 6.0% and 11.0% of a level of carbon atoms present in the graphene quantum dot."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Graphene quantum dots and method of making","description":"A method for forming a graphene quantum dot product includes adding an organic starting material to a vessel and heating the organic starting material to a temperature within 20° C. of the organic sta","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9637443","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.
