      abstract     = {We analyze theoretically the influence of low-dielectric
                      boundaries on the adsorption of flexible polyelectrolytes
                      onto planar and spherical oppositely charged surfaces in
                      electrolyte solutions. We rationalize to what extent polymer
                      chains are depleted from adsorbing interfaces by repulsive
                      image forces. We employ the WKB (Wentzel-Kramers-Brillouin)
                      quantum mechanical method for the Green function of the
                      Edwards equation to determine the adsorption equilibrium.
                      Scaling relations are determined for the critical adsorption
                      strength required to initiate polymer adsorption onto these
                      low-dielectric supports. Image-force repulsion shifts the
                      equilibrium toward the desorbed state, demanding larger
                      surface charge densities and polyelectrolyte linear charge
                      densities for the adsorption to take place. The effect is
                      particularly pronounced for a planar interface in a low-salt
                      regime, where a dramatic change in the scaling behavior for
                      the adsorption-desorption transition is predicted. For the
                      adsorbed state, polymers with higher charge densities are
                      displaced further from the interface by image-charge
                      repulsions. We discuss relevant experimental evidence and
                      argue about possible biological applications of the
                      results.},
