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 ...
On the role of surrounding regions in the fusion peptide in dengue virus infection
(2021-05-01)
Dengue virus infection depends on its fusion with the host membrane, where the binding occurs through interaction between proteins on the virus cell surface and specific viral receptors on target membranes. This process ...
Comportamiento de las películas de bitumen mexicano y sus fracciones de asfalteno y maltenos en la interfase agua-aire
(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. División de Ciencias Básicas e Ingeniería., 2022)
La industria petrolera se ha enfocado en la última década en los bitúmenes y crudos pesados debido al agotamiento de los yacimientos de petróleo. Es por ello que, en este trabajo se estudió la comparación del comportamiento ...
Penicillin-binding proteins (PBPs) determine antibiotic action in Langmuir monolayers as nanoarchitectonics mimetic membranes of methicillin-resistant Staphylococcus aureus
(2022-06-01)
The membrane of methicillin-resistant Staphylococcus aureus (MRSA) contains penicillin-binding proteins (PBPs) in the phospholipidic bilayer, with the protein PBP2a being linked with the resistance mechanism. In this work ...
The insertion of Polybia-MP1 peptide into phospholipid monolayers is regulated by its anionic nature and phase state
(Elsevier Ireland, 2017-10)
Polybia-MP1 or simply MP1 (IDWKKLLDAAKQIL-NH2) is a peptide with broad-spectrum bactericidal activity and a strong inhibitory effect against cancer cells. The aim of this work was to evaluate the effect of biophysical ...
Clearly Detectable, Kinetically Restricted Solid-Solid Phase Transition in cis-Ceramide Monolayers
(American Chemical Society, 2018-10)
Sphingosine [(2S,3R,4E)-2-amino-4-octadecene-1,3-diol] is the most common sphingoid base in mammals. Ceramides are N-acyl sphingosines. Numerous small variations on this canonical structure are known, including the 1-deoxy, ...

Refractive index and thickness determination in Langmuir monolayers of myelin lipids
(Elsevier Science, 2017-05)
Langmuir monolayers at the air/water interface are widely used as biomembrane models and for amphiphilic molecules studies in general. Under controlled intermolecular organization (lateral molecular area), surface pressure, ...
Destabilizing effect of perfluorodecanoic acid on simple membrane models
(Royal Society of Chemistry, 2019-01)
Perfluoroalkyl acids (PFA) are amphiphilic surfactants widely used in industry with several commercial applications. An important feature of these compounds is their non-biodegradability and their tendency to bio-accumulate ...
