abstract = {Polyelectrolytes are macromolecules composed of charged
monomers and exhibit unique properties due to the interplay
of their flexibility and electrostatic interactions. In
solution, they are attracted to oppositely charged surfaces
and interfaces and exhibit a transition to an adsorbed state
when certain conditions are met concerning the charge
densities of the polymer and surface and the properties of
the solution. In this review, we discuss two limiting cases
for adsorption of flexible polyelectrolytes on curved
surfaces: weak and strong adsorption. In the first case,
adsorption is strongly influenced by the entropic degrees of
freedom of a flexible polyelectrolyte. By contrast, in the
strong adsorption limit, electrostatic interactions
dominate, which leads to particular adsorption patterns,
specifically on spherical surfaces. We discuss the
corresponding theoretical approaches, applying a mean-field
description for the polymer and the polymer–surface
interaction. For weak adsorption, we discuss the critical
adsorption behavior by exactly solvable models for planar
and spherical geometries and a generic approximation scheme,
which is additionally applied to cylindrical surfaces. For
strong adsorption, we investigate various polyelectrolyte
patterns on cylinders and spheres and evaluate their
stability. The results are discussed in the light of
experimental results, mostly of DNA adsorption experiments},
