Chitosan derivatives targeting lipid bilayers: Synthesis, biological activity and interaction with model membranes
(2018-02-01)
The antimicrobial activity of chitosan and derivatives to human and plant pathogens represents a high-valued prospective market. Presently, two low molecular weight derivatives, endowed with hydrophobic and cationic character ...
Large cation-selective pores from rat liver peroxisomal membranes incorporated to planar lipid bilayers
(Springer-Verlag, 1986)
Fusion of a highly purified fraction of rat liver peroxisomal membranes to planar lipid bilayers incorporates large, cation-selective voltage-dependent pores. The PK/PCl ratio of these pores, estimated in KCl gradients, ...
The major Thiobacillus ferrooxidans outer membrane protein forms low conductance ion channels in planar lipid bilayers
(1992)
A protein isolated and purified from the outer membrane of the acidophilic, chemolithotrophic bacterium, Thiobacillus ferrooxidans with an oligomeric molecular weight of 90 000 Da (p9O) was incorporated into phosphatidyl ...
Side chain liquid crystalline composites, occurrence of interdigitated bilayer smectic c phases
(2011)
We report on the results of X-ray investigations in two series of polymer monomer composites, PM6Rm-33 and PMnR12-33, which consist of mixtures of achiral liquid crystalline side chain polymers and their monomers. These ...
Spontaneous formation in air of DPPC Supported Lipid Bilayers (SLBs) evaporated in a solvent free process on silicon substrates
(2021)
Artificial membranes are models for biological systems and are important to gain deeper insight into biological membranes and for various applications. We introduce a dry two-step self-assembly method consisting of the ...
Insertion and expulsion mechanism of an amphiphile in a membrane mimetic
(Amer Chemical SOC, 2018)
A theoretical study, validated with experimental data, on the mechanism of insertion/expulsion of an amphiphile from its aggregate is presented. Using molecular dynamics (MD), the equilibrium of tetradecyltrimethylammonium ...
Correlation between the PL and EL emissions of polyfluorene-based diodes using bilayers or polymer blends
(Elsevier Science Sa, 2017)
The electroluminescent (EL) properties of two polyfluorene-based (poly(9,9-di-n-octylfluorenyl-2,7-diyl) (PFO) and poly[(9,9-di-n-octylfluorenyl-2,7-diyl)-alt-(benzo[2,1,3]thiadiazol-4,8-diyl)] (F8BT)) organic light-emitting ...
Theoretical Study of the Molecules in Solution and Phospholipid Bilayers
(Sociedade Brasileira de Bioquímica e Biologia MolecularFoz do Iguaçu, 2013-05-18)
Using Molecular Dynamics simulations and Quantum Mechanical calculations, we study the behavior of molecules with biophysical and pharmacological interest in solution and in phospholipid bilayer.
