Signatures of auxeticity in microgels at low and ultralow crosslinker concentration
Susana Marín-Aguilar, Leah Rank, Emanuela Zaccarelli
Auxetic behavior, characterized by a negative Poisson's ratio, is a counterintuitive mechanical response exhibited, among other systems, by certain polymer networks. Here, through…
Unexpected Behavior of Ultra-Low-Crosslinked Microgels in Crowded Conditions
Susana MarÃn-Aguilar, Emanuela Zaccarelli
Ultra-low-crosslinked (ULC) microgels are among the softest colloidal particles nowadays routinely synthesized experimentally. Despite a growing literature of experimental results,…
A Soft Penetrable Sphere Colloid Model for the Description of Charge and Excluded Volume Interactions in Antibody Solutions
Peter Schurtenberger, Marco Polimeni, Sophia Marzouk +3
Colloid models have frequently been used to successfully describe the influence of protein-protein interactions on antibody solution properties, but they suffer from inherent probl…
Self-induced buckling in hollow microgels
Leah Rank, Emanuela Zaccarelli
Hollow microgels are elastic polymer shells easily realizable in experiments. Recent works have shown the emergence of buckling events in dilute hollow microgels under the effect o…
Soft ULC Microgels at the Interface Interact and Flow as Hertzian-Like Colloids
José Ruiz-Franco, Tom Höfken, Maximilian M. Schmidt +3
Soft pair potentials predict a reentrant liquid phase for high concentrations, a behavior not observed experimentally. Here, very soft microgels confined at an oil-water interface…
Numerical insights on the volume phase transition of thermoresponsive hollow microgels
Leah Rank, Emanuela Zaccarelli
Hollow microgels, consisting of a pNIPAM polymer network with a central cavity, have significant potential due to their tunable softness and encapsulation capabilities. Using molec…
