The fluorescence sensing film for monitoring two-dimensional pH is prepared from the fluorescent dye HPTS-lipo, and HPTS-lipo is embedded by hydrogel D4 in a preparation process. The fluorescent dye HPTS-lipo is prepared by ligating alkylamine into sulfonic acid groups of the fluorescent dye HPTS. Compared with the fluorescent dye HPTS, the pKa value of the modified fluorescent dye HPTS-lipo is significantly varied, so that the fluorescent sensing film is suitable for monitoring different pH values and meets different experimental requirements; and the fluorescent dye HPTS-lipo has better hydrophobicity, can be kept for longer time in environment, and further solves the problem of dye leakage after being embedded by the hydrogel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fluorescent sensing film for pH planar optode, preparation method and application","description":"The present invention provides a fluorescent dye HPTS-lipo for monitoring two-dimensional pH value, a fluorescent sensing film, and use thereof, belonging to the field of two-dimensional pH value moni","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11300510","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.
