Lateral mobility of proteins in liquid membranes revisited
It is shown in this work that, for several integral proteins spanning a large range of sizes, the diffusion coefficient is strongly linked to the protein dimensions. Expand
Effect of a neutral water-soluble polymer on the lamellar phase of a zwitterionic surfactant system.
The results of Freeze-Fracture Electron Microscopy and Small Angle X-ray Scattering experiments show that the addition of the polymer induces the spontaneous formation of highly monodisperse multilayered vesicles above a threshold polymer concentration. Expand
Interaction between poly(ethylene glycol) and two surfactants investigated by diffusion coefficient measurements.
Dynamic light scattering (DLS) and fluorescence recovery after pattern photobleaching (FRAPP) were used to study the interaction of low molecular weight poly(ethylene glycol) (PEG) with micelles ofExpand
Synthesis of Gold Nanoparticles Using Mimosa tenuiflora Extract, Assessments of Cytotoxicity, Cellular Uptake, and Catalysis
Cell viability and cytotoxicity were evaluated in human umbilical vein endothelial cells (HUVEC), and a moderate cytotoxic effect at 24 and 48 h was found, however, toxicity does not behave in a dose-dependent manner. Expand
Importance of molecular interactions in colloidal dispersions
We review briefly the concept of colloidal dispersions, their general properties and some of their most important applications, as well as the basic molecular interactions that give rise to theirExpand
On the computational modeling of the viscosity of colloidal dispersions and its relation with basic molecular interactions
The connection between fundamental interactions acting in molecules in a fluid and macroscopically measured properties, such as the viscosity between colloidal particles coated with polymers, isExpand
Confinement of a hydrophilic polymer in membrane lyotropic phases.
Self-diffusion experiments performed in the lyotropic sponge (L(3)) phase show that the polymer adsorbs onto the surfactant membranes, explaining earlier observations: high polymer concentrations decrease the Gaussian rigidity of the membranes and a vesicular phase is stabilized. Expand
Role of the chemical modification of titanium dioxide surface on the interaction with silver nanoparticles and the capability to enhance antimicrobial properties of poly(lactic acid) composites
In this work, the antimicrobial activity of neat and silanized titanium dioxide deposited with silver nanoparticles was evaluated when it was used as filler in a poly(lactic acid) matrix. TheExpand
Improvement in the energy dissipation capacity of polypropylene composites through a surface modification of titanium dioxide particles with a dicarboxylic acid
Abstract In this work, we modified commercial TiO2 nanoparticles using pimelic acid (PA) as an agent to improve interaction of titanium dioxide (TiO2) into an isotactic polypropylene (iPP) matrix.Expand
Importance of pore length and geometry in the adsorption/desorption process: a molecular simulation study
Discrete potentials can describe properly the liquid vapour boundary that is necessary to model the adsorption of gas molecules in mesoporous systems with computer simulations. Although there areExpand
