      abstract     = {Polyelectrolyte gels are known to undergo significant
                      conformational changes in response to external stimuli such
                      as pH, temperature, or the dielectric constant.
                      Specifically, an increase of the degree of ionization
                      associated with an increasing number of counterions leads to
                      swelling of the network. For a macroscopically large gel,
                      which is electrostatically neutral in its interior, swelling
                      is no longer governed by electrostatic interactions, but
                      rather by the osmotic pressure of counterions. However, this
                      electrostatic neutrality is typically violated for nanogels,
                      because counterions are free to leave a gel particle.
                      Although nanogel-swelling exhibits similar features as
                      swelling of micro- and macrogels, another mechanism has to
                      be relevant. Here, we use molecular dynamics simulations and
                      scaling theory to unravel the structural properties of
                      nanogels upon changing the electrostatic interactions. We
                      demonstrate that the swelling of nanogels is governed by
                      screened electrostatic interactions without a relevant
                      contribution by the counterion osmotic pressure.},
