The cerebrospinal fluid is a dilute suspension of large colloidal macroparticles such as protein molecules and cells. Based on microscopic observations of cerebrospinal fluid samples and some theoretical data the authors could develop a schematic structure of electric double layer around the biomolecules suspended in cerebrospinal fluid. Numerical results show that the averaged diameter of the observed macroparticles is 5,1 Î¼m. We could observe Brownian motions of large biomolecules as a result of thermal nanoparticles movements. Understanding ions composition of cerebrospinal fluid we could state that the compact Stern layer consists of sodium cations
and the Gouy layer of chloride anions.
