Based on an article published in Macromolecules (DOI:10.1021/acs.macromol.7b02722). Multilayer microgels (polymer networks swollen by a solvent) need to be fitted with a core-multishell model due to the different scattering length density in the core and in the two shells. An already implemented version of a core-multishell model exists, but only for sharp interfaces. Like many soft matter particles, microgels do not exhibit a homogeneous density distribution, but rather a fuzziness at the outer periphery (and in the hollow case without a core, also at the inside).
