The issue of critical polyelectrolyte adsorption is intimately coupled to the polymer-mediated bridging attraction between oppositely charged macro-ions immersed in a polymer solution. Moreover, electrostatically driven self-assembly of single-stranded RNA molecules on the interior of positively charged capsids, as it occurs in many spherical and rod-Uke single-stranded viruses, offers another field for potential applications of our theoretical results. The WKB method developed above has recently been implemented to weak polyelectrolyte adsorption under confined conditions [49] and to adsorption onto low-dielectric interfaces [50]. The power of the WKB approach can even be extended to more complicated adsorption situations, such as patchy surfaces, specific charged patterns on concave and convex interfaces, Janus particles, etc., and other (nearly arbitrary) potentials of polyelectrolyte-surface interactions. This might open an avenue to approach more realistic situations of polyelectrolyte adsorption and to quantitatively reproduce experimental results in the future.
