      abstract     = {The bulk modulus, K, quantifies the elastic response of an
                      object to an isotropic compression. For soft compressible
                      colloids, knowing K is essential to accurately predict the
                      suspension response to crowding. Most colloids have complex
                      architectures characterized by different softness, which
                      additionally depends on compression. Here, we determine the
                      different values of K for the various morphological parts of
                      individual nanogels and probe the changes of K with
                      compression. Our method uses a partially deuterated polymer,
                      which exerts the required isotropic stress, and small-angle
                      neutron scattering with contrast matching to determine the
                      form factor of the particles without any scattering
                      contribution from the polymer. We show a clear difference in
                      softness, compressibility, and evolution of K between the
                      shell of the nanogel and the rest of the particle, depending
                      on the amount of cross-linker used in their synthesis.},
