abstract = {Microgels are nanometer-to-micrometer-sized cross-linked
polymer networks that swell when dispersed in a good
solvent. These soft colloids have emerged as versatile
building blocks of smart materials, which are distinguished
by their unique ability to adapt their behavior to changes
in external stimuli. Using X-ray and neutron scattering and
molecular simulation methods, we systematically measured and
modeled the response to crowding of compressible, deformable
microgels with varying cross-link densities and internal
architectures. Our experiments and simulations demonstrate
that incorporating a solvent-filled cavity during chemical
synthesis provides an independent means of controlling
microgel swelling that complements the influence of changing
cross-link density. In other words, knowledge of the content
of cross-links alone cannot be used to define microgel
softness, but microgel architecture is another key property
that affects softness. These results are potentially
important for biomedical applications, such as drug delivery
and biosensing.},
