In this work, different types of magnetic/plasmonic MnFe2O4/Au nanoparticles were prepared, including core-shell and decorated nanoparticles. The structural, spectroscopic and magnetic properties were evaluated. The nanoparticles were covered with a lipid bilayer or entrapped in liposomes.POPH-QREN; FCT Strategic Funding to CF-UM-UP (UID/FIS/04650/2013); FCT Strategic Funding to CQUM (UID/QUI/00686/2016); FCT PhD Grant SFRH/BD/90949/2012info:eu-repo/semantics/publishedVersio
