Charge regulation of complex (bio)colloids

Rudi Podgornik

Abstract: I will present some recent developments in dealing with dissociable charge groups on solvent exposed surfaces of macromolecules. This applies to bulk protein solutions as well as proteinaceous aggregates such as viral shells and enzymatic nanocontainers, providing scaffolding and compartmentalization for chemical engineering on the nano-scale. Charge regulation alters the behavior of chargeable colloidal systems by fundamentally modifying the standard PB (Poisson-Boltzmann) paradigm. I will describe several of these modifications: (i) alterations of not only in the net charge but also in the direction and strength of all higher multipoles of single proteins; (ii) effective charges of proteinaceous aggregates such as virus capsids, (iii) electrostatically driven shape transitions of viral capsids.
