We present a molecular theory to study the adsorption of different species within pH-sensitive hydrogel nanofilms. The theoretical framework allows for a molecular-level description of all the components of the system, and it explicitly accounts for the acid-base equilibrium. We concentrate on the adsorption of hexahistidine, one of the most widely used tags in bio-related systems, particularly...

W eibel-Palade bodies are membrane bound , rod-shaped or-ganelles found exclusively in endothelial cells. These structures were utterly mysterious when Ewald Weibel, working in George Palade's laboratory, first described them in a seminal 1964 JCB paper (1). But it's now known that their distinctive shape is imbued by tightly wound strands of a protein called von Willebrand Factor, which is rel...

Actually, chameleon is the common name for the anole, the best known lizard in our Western Hemisphere.
