Artificial membranes are models for biological systems and are important for applications. We introduce a dry two-step self-assembly method consisting of the high-vacuum evaporation of phospholipid molecules over silicon, followed by a subsequent ann

Fluorescence properties of aurone derivatives: an experimental and theoretical study with some preliminary biological applications
Autor: Nancy Pizarro, Cristian O. Salas, Diego Cortés-Arriagada, Alan R. Cabrera, José Robinson-Duggon, Christian Espinosa-Bustos, Marco Soto-Arriaza, Denis Fuentealba
Publikováno v: Photochemical & Photobiological Sciences. 16:1268-1276
In this paper, we explored the fluorescence properties of eight aurone derivatives bearing methoxy groups and bromine atoms as substituents in the benzene rings. All derivatives showed strong solvatochromic absorption and emission properties in solve

Physicochemical properties of L-alpha dipalmitoyl phosphatidylcholine large unilamellar vesicles: Effect of hydrophobic block (PLA/PCL) of amphipathic diblock copolymers
Autor: Sebastián Bonardd, Karina Flandez, Marco Soto-Arriaza
Publikováno v: Chemistry and physics of lipids. 230
In the present work, we show how amphipathic diblock copolymers affect the physicochemical properties of the lipid bilayer of DPPC liposome. Diblock copolymers proposed for this study are focused in the difference between PLA and PCL hydrophobic bloc

Publikováno v: New Journal of Chemistry. 40:2362-2375
Benzimidazoles presenting intramolecular hydrogen bonding interactions have been normally used to better understand the role of H-bonding in biological processes. Here, we present an experimental and theoretical study of a new compound [2,4-di-tert-b

Effect of the addition of alkanols of different topology to dipalmitoyl-phosphatidylcholine vesicles in the presence of gramicidin
Autor: C. Olivares-Ortega, Marco Soto-Arriaza, E.A. Lissi
Publikováno v: Journal of Colloid and Interface Science. 385:48-57
In the present work, we analyze the effect of incorporation of the nonanol family (e.g., 1-Nonanol (1-N), 5-Nonanol (5-N), and 2,6-Dimethyl-4-Heptanol (2,6-DH)) into DPPC LUVs in the presence of different gramicidin concentrations. The principal aim

The physical study of artificial phospholipid membranes on solid substrates has become a relevant way to gain insights into the physical behavior of cell membranes. The study of mechanical properties of artificial membranes (lab-made) has become poss

Relationship between lipid peroxidation and rigidity in L-α-phosphatidylcholine-DPPC vesicles
Autor: Carlos P. Sotomayor, E.A. Lissi, Marco Soto-Arriaza
Publikováno v: Journal of Colloid and Interface Science. 323:70-74
DPPC incorporation into egg-PC unilamellar vesicles reduces their oxidation rate beyond that expected from the unsaturated lipid dilution. Addition of the unsaturated lipids produces changes in the physical properties of the inner parts of the lipid
