  It is well-known that the swelling behavior of ionic nanogels depends on
their cross-link density, however it is unclear how different topologies should
affect the response of the polyelectrolyte network. Here we perform Monte Carlo
simulations to obtain the equilibrium properties of ionic nanogels as a
function of salt concentration $C_s$ and the fraction $f$ of ionizable groups
in a polyelectrolyte network formed by cross-links of functionality $z$. Our
results indicate that the network with cross-links of low connectivity result
in nanogel particles with higher swelling ratios. We also confirm a de-swelling
effect of salt on nanogel particles.
