Interaction between heterogeneously charged surfaces: Surface patches and charge modulation [PDF]

Physical Review E, 2013
When solid surfaces are immersed in aqueous solutions, some of their charges can dissociate and leave behind charge patches on the surface. Although the charges are distributed heterogeneously on the surface, most of the theoretical models treat them as homogeneous.

Buried Charged Surface in Proteins [PDF]

Structure, 2000
The traditional picture of charged amino acids in globular proteins is that they are almost exclusively on the outside exposed to the solvent. Buried charges, when they do occur, are assumed to play an essential role in catalysis and ligand binding, or in stabilizing structure as, for instance, helix caps.By analyzing the amount and distribution of ...
