The relative hydrophilicity at the interface of a nanoparticle was measured utilizing electron paramagnetic resonance (EPR) spectroscopy. The supramolecular structure was assembled from spin-labeled peptide amphiphiles (PA) derived from N-c...
Local pH and Effective p K of a Polyelectrolyte Chain: Two Names for One Quantity? [0.03%]
多电性链的局部pH和有效pK:两个名称 一个量?
Anastasiia Murmiliuk,Peter Košovan,Miroslav Janata et al.
Anastasiia Murmiliuk et al.
In recent experiments, the "local pH" near polyelectrolyte chains was determined from the shift in the effective acidity constant of fluorescent pH indicators attached to the macromolecules. This indirect determination raises the question i...
