This paper describes a novel material based on thermo responsive PNIPAm nanopillars with amplified surface properties through the incorporation of Fe3O4 nanoparticles. The incorporation of magnetic nanoparticles into the nanopillars, prepared via surface-initiated atomtransfer radical polymerization in anodized aluminum oxide templates, sharply increased their stiffness and hydrophobicity when increasing the temperature above the volume phase transition temperature. Furthermore, their magnetic response turned out to be proportional to the amount of the incorporated nanoparticles. The possibility of sharply increasing the stiffness with a temperature variation close to the human body temperature paves the way to the application of these substrates as \u201csmart\u201d scaffolds for cell culture. Additionally, the presence of superparamagnetic nanoparticles in the nanopillars offers the possibility of using these nanostructured systems for magnetic hyperthermia.<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" Nanoscale, 2018, 10, 1189 Thermo-responsive PNIPAm nanopillars displaying amplified responsiveness through the incorporation of nanoparticles Juan M.
