Layer‐by‐Layer Deposition of Polyelectrolytes—A Versatile Tool for the In Vivo Repair of Blood Vessels

Layer-by-layer adsorption of polygenic polyelectrolytes is a promising method of treatment in which multilayers are formed on the inner arterial wall (see scheme). An advantage of this technique, which has already proved successful in animal models, is that it is very simple to apply, in contrast to in situ polymerization, which requires irradiation with UV light. Furthermore, it is rapid and allows the incorporation of active drugs in the layer.
