Large Changes in Protonation of Weak Polyelectrolyte Brushes with Salt Concentration—Implications for Protein Immobilization
[Image: see text] We report for the first time that the protonation behavior of weak polyelectrolyte brushes depends very strongly on ionic strength. The pK(a) changes by one pH step per order of magnitude in salt concentration. For low salt concentrations (∼1 mM), a very high pH is required to depr...
