Biological protein pores and pore-forming peptides can generate a pathway for the flux of
ions and other charged or polar molecules across cellular membranes. In nature, these …

New techniques have been introduced or pushed forward to render this model system more
powerful. Dynamical light scattering allows us to quantify, in non-pertubative way …

A recently introduced real-space lattice methodology for solving the three-dimensional
Poisson-Nernst-Planck equations is used to compute current-voltage relations for ion …

Continuum theories of electrolytes are widely used to describe physical processes in various
biological systems. Although these are well-established theories in macroscopic situations, it …

Although the crystallographic structure of the bacterial porin OmpF has been known for a
decade, the physical mechanisms of its ionic selectivity are still under investigation. We …

Charged lipids constitute a substantial fraction of all membrane lipids. Their charges vary in
quantity and distribution within their headgroup regions. In long range interactions, their …

Ion channels are formed by specific proteins embedded in the cell membrane and provide
pathways for fast and controlled flow of selected ions down their electrochemical gradient …

The Poisson-Nernst-Planck (PNP) theory of electro-diffusion is reviewed. Techniques for
numerical solution of the three-dimensional PNP equations are summarized, and several …

A partial characterization of the ion channels formed by the SARS coronavirus (CoV)
envelope (E) protein was previously reported (C. Verdiá-Báguena et al., 2012 [12]). Here …

The association between monovalent salts and neutral lipid bilayers is known to influence
global bilayer structural properties such as headgroup conformational fluctuations and the …
