支撑胶体和表面科学的经典Derjaguin-Landau-Verwey-Overbeek理论被证明是有缺陷的，特别是在生物盐浓度下。这部分是因为忽略了作用在离子上的色散力。如果适当地包括这些因素，就会得到非常不同的结果。这些结果对生物和普通胶体系统在中等盐浓度下具有重大意义。
The classical Derjaguin-Landau-Verwey-Overbeek theory that underpins colloid 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 and for ordinary colloid systems at moderate salt concentrations.
