The effect of ionic strength on the structural organization of dioctadecyldimethylammonium bromide in aqueous solution
(Springer, 2004-01-01)
High-curvature and stabilized vesicles of dioctadecyldimethylammonium bromide (DODABr) can be formed spontaneously in aqueous electrolytic solution. It is shown by cryo-transmission electron microscopy that 5.0 mM DODABr ...

Phase transition in dioctadecyldimethylammonium bromide and chloride vesicles prepared by different methods
(Elsevier B.V., 2000-04-01)
The gel to liquid crystalline phase transition of the double-chained cationic dioctadecyldimethylammonium chloride and bromide (DODAX, X = Cl- or Br-) in aqueous vesicle dispersions prepared by non-sonication, sonication ...
Conformational changes, from β-strand to α-helix, of the fatty acid-binding protein ReP1-NCXSQ in anionic lipid membranes: dependence with the vesicle curvature
(Springer, 2017-07)
We studied the conformational changes of the fatty acid-binding protein ReP1-NCXSQ in the interface of anionic lipid membranes. ReP1-NCXSQ is an acidic protein that regulates the activity of the Na+/Ca2+ exchanger in squid ...
Membrane topology modulates β-galactosidase activity against soluble substrates
(Elsevier Science, 2002-11-06)
The effect of bio-surfaces of contrasting curvature, on the kinetic parameters of ortho-nitrophenyl-β-D-galactopiranoside hydrolysis catalyzed by E. coli β-galactosidase, was investigated. The self-aggregating state and ...
Controlling the generation of bilayer and multilayer vesicles in block copolymer/epoxy blends by a slow photopolymerization process
(Royal Society of Chemistry, 2017-09)
Vesicles are a highly attractive morphology to achieve in micellar dispersions of block copolymers (BCP) in epoxy thermosets due to the fact that small amounts can affect a large volume fraction of the matrix, a fact that ...
Chemical and morphological effects of the contraceptive hormone 17 α-ethynylestradiol on fluid lipid membranes
(2021-08-01)
The lack of studies involving the effects in human health associated with the chronic ingestion of pollutants lead to the path of investigating the action of these compounds in cell membrane models. We demonstrated the ...
