Modulation of the domain topography of biphasic monolayers of stearic acid and dimyristoyl phosphatidylcholine
(Elsevier Ireland, 2012-02)
The phase diagram of mixed monolayers composed of dimyristoyl phosphatidylcholine (DMPC) and stearic acid (SA) on different subphases was previously reported. It was observed that on acid subphases, liquid-condensed domains ...
Surface interactions, thermodynamics and topography of binary monolayers of Insulin with dipalmitoylphosphatidylcholine and 1-palmitoyl-2-oleoylphosphatidylcholine at the air/water interface
(Academic Press Inc Elsevier Science, 2016-02-15)
The molecular packing, thermodynamics and surface topography of binary Langmuir monolayers of Insulin and DPPC (dipalmitoylphosphatidylcholine) or POCP (1-palmitoyl-2-oleoylphosphatidylcholine) at the air/water interface ...
Surface mixing of products and substrate of PLA2 in enzyme-free mixed monolayers reproduces enzyme-driven structural topography
(Elsevier Science, 2013-05)
It was proposed that topographic changes in lipid monolayers hydrolyzed by lipolytic enzymes such as Phospholipase A2 (PLA2) are a consequence of enzyme activity at the surface. Lateral packing defects that arise from lipid ...
N-Acyl Chain in Ceramide and Sphingomyelin Determines Their Mixing Behavior, Phase State, and Surface Topography in Langmuir Films
(American Chemical Society, 2014-06)
Sphingolipids are membrane lipids composed by a long chain aminediol base, usually sphingosine, with a N-linked fatty acyl chain whose quality depends on the membrane type. The effect of length and unsaturation of the ...
Surface characterization and study of Langmuir films of poly(4-vinylpyridine) quaternized with n-alkylbromide
(JOHN WILEY & SONS LTD, 2001)
The surface behaviour of poly(4-vinylpyridine)s (P4VP) quaternized with four different alkyl chains (pentyl, hexyl, octyl and decy bromide) were studied. Surface pressure-area isotherms (pi -A) at the air-water interface ...
Hydrophobic silver nanoparticles interacting with phospholipids and stratum corneum mimic membranes in Langmuir monolayers
(Academic Press Inc Elsevier Science, 2019-05)
The interaction of hydrophobic silver nanoparticles with different phospholipids and stratum corneum mimic (SCM) membranes is studied in Langmuir monolayers. Thus, silver nanoparticles coated with oleic acid (AgNP-OA) were ...
Myristoylation and Oligonucleotide Interaction Modulate Peptide and Protein Surface Properties: The Case of the HIV-1 Matrix Domain
(American Chemical Society, 2018-05)
Myristoylated proteins typically develop a tight association with membranes. One example is the matrix domain (MA) of the HIV-1 Gag protein. In addition, MA is able to bind the Sel25 RNA sequence, a ligand that can act as ...
Cyclic voltammetric and scanning electrochemical microscopic study of thiolated beta-cyclodextrin adsorbed on a gold
(AMER CHEMICAL SOC, 2003-04-15)
Potassium ferricyanide ([Fe(CN)(6)](3-)) reduction and ferrocenemethanol (Fe-OH) oxidation at a beta-cyclodextrin (beta-CD)-modified gold electrode were investigated by cyclic voltammetry (CV) and scanning electrochemical ...
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 ...
Distinctive Interactions of Oleic Acid Covered Magnetic Nanoparticles with Saturated and Unsaturated Phospholipids in Langmuir Monolayers
(American Chemical Society, 2014-04)
The growing number of innovations in nanomedicine and nanobiotechnology are posing new challenges in understanding the full spectrum of interactions between nanomateriales and biomolecules at nano-biointerfaces. Although ...
