Tuning Liposome Membrane Permeability by Competitive Peptide Dimerization and Partitioning-Folding Interactions Regulated by Proteolytic Activity
Membrane active peptides are of large interest for development of drug delivery vehicles and therapeutics for treatment of multiple drug resistant infections. Lack of specificity can be detrimental and finding routes to tune specificity and activity of membrane active peptides is vital for improving their therapeutic efficacy and minimize harmful side effects. We describe a de novo designed mem...
متن کاملAnomalous interactions in confined charge-stabilized colloid
Charge-stabilized colloidal spheres dispersed in weak 1:1 electrolytes are supposed to repel each other. Consequently, experimental evidence for anomalous long-ranged like-charged attractions induced by geometric confinement inspired a burst of activity. This has largely subsided because of nagging doubts regarding the experiments’ reliability and interpretation. We describe a new class of ther...
متن کاملDepletion interactions in colloid-polymer mixtures.
We present a neutron-scattering study of depletion interactions in a mixture of a hard-sphere-like colloid and a nonadsorbing polymer. By matching the scattering length density of the solvent with that of the polymer, we measured the partial structure factor Sc(Q) for the colloidal particles. It is found that the measured Sc(Q) for different colloid and polymer concentrations can be well descri...
متن کاملRepulsive depletion interactions in colloid–polymer mixtures
Depletion forces in colloidal systems are known to be entirely attractive, as long as the background of macromolecules is small enough that an ideal gas approach is valid. At higher densities, however, structural correlation effects of the macromolecules which lead to additional repulsive parts in the depletion interaction, have to be taken into account. We have measured the depletion interacti...
متن کاملInteractions in mixtures of colloid and polymer
2014 We report results of light scattering study of interactions in a mixture of a surfactantstabilized colloid and hydrogenated polyisoprene polymer. With a virial expansion the smallangle scattering intensity from the mixture is calculated as a function of colloid and polymer concentrations. Using the obtained formula we measured the mutual excluded volume between a polymer molecule and a col...
