Query: Charged dendrimers revisited: Effective charge and surface potential of
  dendritic polyglycerol sulfate   We investigate key electrostatic features of charged dendrimers at hand of
the biomedically important dendritic polyglycerol sulfate (dPGS) macromolecule
using multi-scale computer simulations and Zetasizer experiments. In our
simulation study, we first develop an effective mesoscale Hamiltonian specific
to dPGS based on input from all-atom, explicit-water simulations of dPGS of low
generation. Employing this in coarse-grained, implicit-solvent/explicit-salt
Langevin dynamics simulations, we then study dPGS structural and electrostatic
properties up to the sixth generation. By systematically mapping then the
calculated electrostatic potential onto the Debye-H\"uckel form -- that serves
as a basic defining equation for the effective charge -- we determine
well-defined effective net charges and corresponding radii, surface charge
densities, and surface potentials of dPGS. The latter are found to be up to one
order of magnitude smaller than the bare values and consistent with previously
derived theories on charge renormalization and weak saturation for high
dendrimer generations (charges). Finally, we find that the surface potential of
the dendrimers estimated from the simulations compare very well with our new
electrophoretic experiments.
