Förster resonance energy transfer-based anion-responsive nanoemulsion optodes: the importance of fluorescent dye liquid lipophilicity and ionophore–dye interaction for stable and background-free anion response
Abstract
dye and the anion ionophore are effective in suppressing background signals. The optimized FRET-NE optode composition exhibited approximately 10-fold higher sensitivity compared to conventional non-FRET sensors. These findings suggest that the application of FRET using fluorescent dye liquids holds great promise for dramatically enhancing the sensitivity of conventional NE optodes.
