Here, we investigate the effective interactions and the dynamics of hollow microgel suspensions at different temperatures just below the volume phase transition. Despite the particles becoming mechanically stiffer as solvent quality worsens, the extracted effective interactions appear to be softer with increasing temperature. This counterintuitive behavior results from a decrease in monomer repulsion, consistent with a Hertzian description. Bulk simulations show that an effective fluid representation is very accurate in describing the structure of monomer-resolved systems, quantified by their radial distribution function, in an extended range of packing fractions well beyond random close packing. Instead, dynamical observables, such as self-diffusion coefficient and collective relaxation times, are only qualitatively captured, with a systematically faster dynamics observed in coarse-grained models due to the absence of internal degrees of freedom. These results identify hollow microgels as ideal elastic shells, interacting as Hertzian particles, well beyond the two-body regime, as opposed to standard microgels, where such an effective description is only valid in the fluid region of the phase diagram.<\/jats:p>","DOI":"10.1021\/acs.macromol.6c01002","type":"journal-article","created":{"date-parts":[[2026,7,27]],"date-time":"2026-07-27T09:20:33Z","timestamp":1785144033000},"page":"8777-8787","source":"Crossref","is-referenced-by-count":2,"title":["Effective Interactions\nand Dynamical Properties of\nThermoresponsive Hollow Microgels"],"prefix":"10.1021","volume":"59","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-3411-1184","authenticated-orcid":true,"given":"Leah","family":"Rank","sequence":"first","affiliation":[{"name":"Sapienza University of Rome , , Piazzale Aldo Moro 2 , ,","place":["Roma, Italy, 00185"]},{"name":"CNR Institute of Complex Systems, Uos Sapienza , Piazzale Aldo Moro 2 , ,","place":["Roma, Italy, 00185"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angel J.","family":"Moreno","sequence":"additional","affiliation":[{"name":"Centro de Fi\u0301sica de Materiales (CFM-MPC), CSIC-UPV\/EHU , P Manuel Lardizabal 5 , ,","place":["Donostia, Spain, E-20018"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0032-8906","authenticated-orcid":true,"given":"Emanuela","family":"Zaccarelli","sequence":"additional","affiliation":[{"name":"Sapienza University of Rome , , Piazzale Aldo Moro 2 , ,","place":["Roma, Italy, 00185"]},{"name":"CNR Institute of Complex Systems, Uos Sapienza , Piazzale Aldo Moro 2 , ,","place":["Roma, Italy, 00185"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,7,27]]},"reference":[{"key":"2026081110071847500_cit1","doi-asserted-by":"publisher","first-page":"340","DOI":"10.1038\/320340a0","article-title":"Phase Behavior of Concentrated Suspensions of Nearly\nHard Colloidal Spheres","volume":"320","author":"Pusey","year":"1986","journal-title":"Nature"},{"key":"2026081110071847500_cit2","doi-asserted-by":"publisher","first-page":"4895","DOI":"10.1021\/acs.macromol.9b00099","article-title":"Connecting\nElasticity and Effective Interactions of Neutral Microgels: The Validity\nof the Hertzian Model","volume":"52","author":"Rovigatti","year":"2019","journal-title":"Macromolecules"},{"key":"2026081110071847500_cit3","doi-asserted-by":"publisher","first-page":"14861","DOI":"10.1021\/acsnano.0c03966","article-title":"Crystal-to-Crystal Transitions in\nBinary Mixtures of\nSoft Colloids","volume":"14","author":"Immink","year":"2020","journal-title":"ACS Nano"},{"key":"2026081110071847500_cit4","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.120.078003","article-title":"Crystal-to-Crystal Transition of Ultrasoft Colloids\nunder Shear","volume":"120","author":"Ruiz-Franco","year":"2018","journal-title":"Phys.
