Kinnear, Calum Balog, Sandor Rothen-Rutishauser, Barbara Petri-Fink, Alke 2014-12-01 The directed self-assembly of gold nanoparticles through the crystallization of surface-grafted polyethylene oxide (PEO) in ethanol–water mixtures is described. This process is fully reversible and tunable through either the size of the core or the polymeric coating. Characterization by X-ray scattering and electron microscopy of the self-assembled structures reveals order at the nanoscale, typically not the case for thermoresponsive gold nanoparticles coated with lower or upper critical solution temperature polymers. A further novelty is the result of selective binding of calcium ions to the PEO in the fluid state: a reversible thermoresponsive transition become irreversible. application/pdf https://folia.unifr.ch/global/documents/304017 https://folia.unifr.ch/documents/304017/files/pet_trs.pdf https://folia.unifr.ch/documents/304017/files/pet_trs_sm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1002/marc.201400457 info:eu-repo/semantics/openAccess License undefined Macromolecular Rapid Communications. - 2014, vol. 35, no. 23, p. 2012–2017 info:eu-repo/classification/udc/54 Thermally reversible self-assembly of nanoparticles via polymer crystallization http://purl.org/coar/resource_type/c_6501
