  In many biological processes highly charged biomolecules are adsorbed into
oppositely charged surfaces of macroions and membranes. They form strongly
correlated structures close to the surface which can not be explained by the
conventional Poisson-Boltzmann theory. Many of the flexible biomolecules can be
described by Gaussian polymers. In this work strong coupling theory is used to
study the adsorption of highly charged Gaussian polyelectrolytes. Two cases of
adsorptions are considered, when the Gaussian polyelectrolytes are confined a)
by one charged wall, and b) between two charged walls. The effects of salt and
the geometry of the polymers on their adsorption- depletion transitions in the
strong coupling regime are discussed.
