Non-monotonic swelling of a macroion due to correlation-induced charge inversion
Brian Skinner, B. I. Shklovskii
It is known that a large, charged body immersed in a solution of multivalent counterions may undergo charge inversion as the counterions adsorb to its surface. We use the theory of…
Effective charge and free energy of DNA inside an ion channel
Jingshan Zhang, B. I. Shklovskii
Translocation of a single stranded DNA (ssDNA) through an alpha-hemolysin channel in a lipid membrane driven by applied transmembrane voltage V was extensively studied recently. Wh…
Conductivity of a suspension of nanowires in a weakly conducting medium
Tao Hu, A. Yu. Grosberg, B. I. Shklovskii
We study macroscopic electrical or thermal conductivity of a composite made of straight or coiled nanowires suspended in poorly conducting medium. We assume that volume fraction of…
Self-energy limited ion transport in sub-nanometer channels
Douwe Jan Bonthuis, Jingshan Zhang, Breton Hornblower +3
The current-voltage characteristics of the alpha-Hemolysin protein pore during the passage of single-stranded DNA under varying ionic strength, C, are studied experimentally. We ob…
How does a protein search for the specific site on DNA: the role of disorder
Tao Hu, B. I. Shklovskii
Proteins can locate their specific targets on DNA up to two orders of magnitude faster than the Smoluchowski three-dimensional diffusion rate. This happens due to non-specific adso…
Ion exchange phase transitions in "doped" water--filled channels
J. Zhang, A. Kamenev, B. I. Shklovskii
Ion transport through narrow water--filled channels is impeded by a high electrostatic barrier. The latter originates from the large ratio of the dielectric constants of the water…
