Ion fluxes through nano-pores and transmembrane channels
José Rafael Bordin, Alexandre Diehl, Marcia C. Barbosa +1
We introduce an implicit solvent Molecular Dynamics approach for calculating ionic fluxes through narrow nano-pores and transmembrane channels. The method relies on a dual-control-…
Counterion correlations and attraction between like-charged macromolecules
Alexandre Diehl, Humberto A. Carmona, Yan Levin
A simple model is presented for the appearance of attraction between two like charged polyions inside a polyelectrolyte solution. The polyions are modeled as rigid cylinders in a c…
Charge inversion in DNA-amphiphile complexes: Possible application to gene therapy
P. S. Kuhn, Y. Levin, M. C. Barbosa
We study a complex formation between the DNA and cationic amphiphilic molecules. As the amphiphile is added to the solution containing DNA, a cooperative binding of surfactants to…
Complexation of DNA with Cationic Surfactant
P. S. Kuhn, Marcia C. Barbosa, Y. Levin
Transfection of an anionic polynucleotide through a negatively charged membrane is an important problem in genetic engineering. The direct association of cationic surfactant to DNA…
Donnan equilibrium and the osmotic pressure of charged colloidal lattices
M. N. Tamashiro, Yan Levin, Marcia C. Barbosa
We consider a system composed of a monodisperse charge-stabilized colloidal suspension in the presence of monovalent salt, separated from the pure electrolyte by a semipermeable me…
Melting of a colloidal crystal
P. S. Kuhn, A. Diehl, Y. Levin +1
A melting transition for a system of hard spheres interacting by a repulsive Yukawa potential of DLVO form is studied. To find the location of the phase boundary, we propose a simp…
