Structure and interactions between charged lipid membranes in the presence of multivalent ions

L Fink, A Steiner, O Szekely, P Szekely, U Raviv - Langmuir, 2019 - ACS Publications
When aqueous salt solutions contain multivalent ions (like Ca2+ or Mg2+), strong correlation
effects may lead to ion-bridging, net attraction, and tight-coupling between like-charged …
