  • Title: A FRET based pH probe with a broad working range applicable to referenced ratiometric dual wavelength and luminescence lifetime read out.
    Author: Meier RJ, Simbürger JM, Soukka T, Schäferling M.
    Journal: Chem Commun (Camb); 2015 Apr 11; 51(28):6145-8. PubMed ID: 25747771.
    Abstract:
    A luminescent probe for determination of pH was designed based on a Förster resonance energy transfer (FRET) system, combining a europium chelate as the donor and carboxynaphtho-fluorescein as a pH sensitive acceptor. The FRET system enables referenced pH detection in an exceptional broad dynamic range from pH 3 to 9.
