Specific ion effects: Why DLVO theory fails for biology and colloid systems - art. no. 168103

The classical Derjaguin-Landau-Verwey-Overbeek theory that underpins colloi d and surface science is shown to be flawed, especially at biological salt concentrations. This is in part because the dispersion forces acting on the ions are ignored. When these are included properly very different results are obtained. These results have substantial implications for biological an d for ordinary colloid systems at moderate salt concentrations.
