Plot of the hydrodynamic radii of all core-shell microgels in the fully swollen state (10 °C, blue symbols) and in the collapsed state (55 °C, red symbols) against the PNIPMAM fraction of the shell at pH = 7 (squares) and pH = 4 (circles). The magenta line indicates the hydrodynamic radius of the fully collapsed core (pH = 4, 55 °C). All hydrodynamic radii were obtained from angle-dependent PCS measurements.
