Query: Adsorption of polyelectrolytes on charged microscopically patterned
  surfaces   In the present study, we have investigated, using Monte Carlo simulations
(MC), the adsorption of polyelectrolytes on the charged nanopatterned surfaces.
Different surface patterns were considered and we noticed that the amount of
adsorption is directly dependent on the size of the domains. Also in the case
of checkerboard configuration, it was observed that the polyelectrolytes are
aligned along the diagonal of square domains.
