  • New Fluorescent Optical pH Sensors with Minimal Effects of Ionic Strength
    Bernhard Weidgans
    There is still a lack of commercial applications of pH sensors due to the decisive disadvantage that the signal is depending on the ionic strength of the sample. pH is defined as the negative logarithm of the activity of protons in aqueous solution, while the optical parameter (e.g. change of absorption or fluorescence) correlates with the concentration of the pH-sensitive dye....
