Key Points

  • The aim was to develop a sensitive FRET-based optode for detecting anions by examining the role of dye lipophilicity and interactions.
  • Fabricated a FRET-based nanoemulsion optode
  • Evaluated fluorescent dye's lipophilicity
  • Assessed the interaction between ionophore and dye
  • Analyzed the optode's anion sensitivity
  • Achieved high sensitivity for anion detection
  • Demonstrated a background-free response
  • Showed the importance of dye lipophilicity in performance
  • Highlighted ionophore-dye interaction effects

Abstract

In this study, we fabricated and evaluated a highly sensitive Förster Resonance Energy Transfer (FRET) based anion-responsive nanoemulsion optode (FRET-NE optode), using the originally-developed lipophilic fluorescent dye liquid. When the...
