Abstract

The isoperichoric focusing transport phenomena were recently described by a rigorous theoretical model. Contrary to the generally accepted supposition that a density gradient forming liquid in isopycnic focusing should behave as continuum regarding the focused species, the model predicts the focusing with no a priori imposed size ratio of the focused to the density gradient forming species. This prediction was evidenced by focusing of the polyaniline nanosize particles in a density gradient formed by colloidal silica particles suspended in water. The size ratio of the polyaniline to silica particles was low.
