Can we use area per surfactant as a quantitative test model of specific ion effects?
Zemb, Th; Belloni, L.; Dubois, M.; Aroti, Andria; Leontidis, Epameinondas (2004)The three main currently proposed approaches for understanding specific ion effects are briefly described. In some experimentally well defined and simplified situations, one can decouple ion specificity effects from all ...

Effects of hofmeister anions on DPPC langmuir monolayers at the air-water interface
Aroti, Andria; Leontidis, Epameinondas; Maltseva, E.; Brezesinski, G. (2004)In this work we investigated the effect of sodium salts of different monovalent anions belonging to the Hofmeister series on Langmuir monolayers of DPPC (1,2-dipalmitoyl phosphatidylcholine). The salts used were NaCl, NaBr, ...

Effects of monovalent anions of the Hofmeister series on DPPC lipid bilayers part I: Swelling and in-plane equations of state
Aroti, Andria; Leontidis, Epameinondas; Dubois, M.; Zemby, T. (2007)Aiming to improve understanding of the mechanisms behind specific anion effects in biological systems we have studied the effects of sodium salts of simple monovalent anions belonging to the Hofmeister series on the bilayers ...

Effects of monovalent anions of the Hofmeister series on DPPC lipid bilayers part II: Modeling the perpendicular and lateral equation-of-state
Leontidis, Epameinondas; Aroti, Andria; Belloni, L.; Dubois, M.; Zemby, T. (2007)The effects of Hofmeister anions on the perpendicular and lateral equation-of-state (EOS) of the dipalmitoylphosphatidylcholine lamellar phase discussed in the companion article are here examined using appropriate free ...

Liquid expanded monolayers of lipids as model systems to understand the anionic hofmeister series: 1. A tale of models
Leontidis, Epameinondas; Aroti, Andria; Belloni, L. (2009)In this work, we use Langmuir monolayers of dipalmitoyl phosphatidylcholine (DPPC) as model systems to enhance the understanding of specific anion effects in physicochemical and biological systems. The 298 K isotherms ...

Liquid expanded monolayers of lipids as model systems to understand the anionic hofmeister series: 2. Ion partitioning is mostly a matter of size
Leontidis, Epameinondas; Aroti, Andria (2009)In the preceding paper of this series [Leontidis, E.

Monolayers, bilayers and micelles of zwitterionic lipids as model systems for the study of specific anion effects
Aroti, Andria; Leontidis, Epameinondas; Dubois, M.; Zemb, T.; Brezesinski, G. (2007)This work is a review of the effect of different monovalent anions (belonging to the Hofmeister series) on a single model amphiphile, phosphatidylcholine molecules in contact with water, in three different geometries, ...

Vibrational sum frequency generation spectroscopic investigation of the interaction of thiocyanate ions with zwitterionic phospholipid monolayers at the air-water interface
Viswanath, P.; Aroti, Andria; Motschmann, H.; Leontidis, Epameinondas (2009)Thiocyanate (SCN-) is a highly chaotropic anion of considerable biological significance, which interacts quite strongly with lipid interfaces. In most cases it is not exactly known if this interaction involves direct binding ...
