Evidence of photoinduced lipid hydroperoxidation in Langmuir monolayers containing Eosin Y
(2018-11-01)
Photodynamic therapy (PDT) efficiency depends on many factors including the incorporation of the photosensitizer (PS) in cell membranes and possible lipid hydroperoxidation. In this study, we show that hydroperoxidation ...
The lipid composition of a cell membrane modulates the interaction of an antiparasitic peptide at the air-water interface
(Elsevier B.V., 2011-07-01)
The antiparasitic property of peptides is believed to be associated with their interactions with the protozoan membrane, which calls for research on the identification of membrane sites capable of peptide binding. In this ...
Domain size polydispersity effects on the structural and dynamical properties in lipid monolayers with phase coexistence
(Royal Society of Chemistry, 2018-02-10)
In lipid monolayers with phase coexistence, domains of the liquid-condensed phase always present size polydispersity. However, very few theoretical works consider size distribution effects on the monolayer properties. ...
Influence of spontaneous curvature on the line tension of phase-coexisting domains in a lipid monolayer: A Landau-Ginzburg model
(American Institute of Physics, 2020-02-03)
The line tension between two coexisting phases of a binary lipid monolayer in its fluid state has contributions not only from the chemical mismatch energy between the two different lipid types but also from the elastic ...
Interaction of dextran derivatives with lipid monolayers and the consequential modulation of the film properties
(Elsevier Ireland, 2017-04)
Polysaccharides have been associated with various biological functions through their binding to membranes, but their specific role is still under debate. The aim of this work was to study the interaction of cationic and ...
Improved prediction of bilayer and monolayer properties using a refined BMW-MARTINI force field
(Elsevier Science, 2016-08-31)
Coarse-grained (CG) models allow enlarging the size and time scales that are reachable by atomistic molecular dynamics simulations. A CG force field (FF) for lipids and amino acids that possesses a polarizable water model ...
Comparative study of liponucleosides in Langmuir monolayers as cell membrane models
(ELSEVIER SCIENCE BV, 2011)
Liponucleosides may assist the anchoring of nucleic acid nitrogen bases into biological membranes for tailored nanobiotechnological applications. To this end precise knowledge about the biophysical and chemical details at ...

(Elsevier B.V., 2011-01-01)
Liponucleosides may assist the anchoring of nucleic acid nitrogen bases into biological membranes for tailored nanobiotechnological applications. To this end precise knowledge about the biophysical and chemical details at ...
A constant area monolayer method to assess optimal lipid packing for lipolysis tested with several secreted phospholipases A2
(Elsevier Science, 2015-10)
We present an analysis of lipid monolayer hydrolysis at a constant area to assess the optimal lateral surface pressure value (Πopt) and thus, the surface packing density of the lipid, at which the activity of a given ...
Phenylalanine interaction with lipid monolayers at different pHs
(Elsevier Science, 2015-04)
The influence of Phe on the surface pressure of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) monolayers at the air?water interface was studied at different initial surface pressures (26 and 40 mN/m) and two pHs (5.0 ...
