Exclusion zone formation next to the surface of contact lenses
Апстракт
Next to the hydrophilic surfaces is found existence of solute-free interfacial zones i.e. exclusion zones. It appears that their properties are different than those in bulk water, and that their width can be up to several hundreds of micrometers. From physiological point of view parallel can be drawn between zone of exclusion and tear film. Both structures appear next to the sort of membrane. In this research different kinds of lenses are placed into chamber and washed with solutions of different dilutions.
All lenses were rigid permeable, with difference of additionally added materials. For solutions are used deionized water and solution
for contact lenses with added carboxylate microspheres. Interaction between differently concentrated microspheres and these liquids are observed microscopically and recorded with high resolution digital camera. We report here that microscopic observations show exclusion next to the surface of all lenses, and that they were not dependent on materia...l of lenses, nor of solutions which are used. This research showed that solutes in aqueous suspensions extensively exclude in the vicinity of biological interfaces.
