Like-charge attraction
As we learned from mean-field theory, like-chared particles repel. However, in the last decade, like-charge polyelectrolyte attraction was observed in the presence of multivalent ions in a variety of biological systems, including DNA, F-actin, microtubules, and filamentous viruses. Considering the fundermental role DNA played in the lifecycle, we find like-charge attraction is not only physical...
متن کاملLong-range attraction between charge-mosaic surfaces across water.
We have measured directly the forces across water between hydrophilic surfaces covered with a random mosaic of positive and negative charged domains. We find a strong, long-ranged attraction between them at a surface separation comparable with the charge domain size (many tens of nanometers). This attraction persists at higher salt concentration, but its range then becomes comparable to the Deb...
متن کاملIon multivalence and like-charge polyelectrolyte attraction.
It is known empirically that multivalent ions generate attractions between like-charged polyelectrolytes, with different valence requirements for different systems. How multivalent must an ion be before it can condense a given polyelectrolyte? Using charge-tunable M13 virus rods and a family of artificial homologous "dumbbell" divalent ions of different sizes, we have constructed a multivalent ...
متن کاملLike-Charge Attraction through Hydrodynamic Interaction
We demonstrate that the attractive interaction measured between likecharged colloidal spheres near a wall can be accounted for by a nonequilibrium hydrodynamic effect. We present both analytical results and Brownian dynamics simulations which quantitatively capture the onewall experiments of Larsen and Grier (Nature 385, 230, 1997).
متن کاملLike-charge attraction and hydrodynamic interaction
We demonstrate that the attractive interaction measured between like-charged colloidal spheres near a wall can be accounted for by a nonequilibrium hydrodynamic effect. We present both analytical results and Brownian dynamics simulations which quantitatively capture the one-wall experiments of Larsen and Grier [Nature (London) 385, 230 (1997)], using a single unmeasured parameter.
