The proposed project aims the development of nanomaterials with specific and multiple functionalities. The idea is to prepare superparamagnetic iron oxide nanoparticles and functionalize their surfaces with different phosphonic acid-terminated polymers, combining the thermoresponsive PNIPAM (poly (N-isopropylacrylamide)) and PEO (poly(ethyleneoxide)) to modulate the nanoparticles interfacial and self-assembly properties. The co-addition of these two polymers would also fine tune the temperature-induced phase transition reversibility. The potential applicability of the prepared hybrid materials as biomarkers for biological applications will be investigated. The combination of a thermoresponsive polymer and a magnetic nanoparticle into a single material with intermediate wettability and possibly a surface organization (patchy or Janus) might pave the way to novel smart nanomaterials applications.
