“…These important applications are based in the fact that a PMHM-film has instant reaction and contactless control, because it responds to an external magnetic field. Additional applications could also be obtained for PMHM-films in considering that magnetic nanoparticles are very important due to their potential integration in a broad range of technological applications, extending from magnetic fluids (Jiang et al, 2014;Goncalves et al, 2015), catalysis (Jiang et al, 2014Tan et al, 2015), ultrahigh-density magnetic storage media (Jiang et al, 2014;Galloway et al, 2015), biotechnology and biomedicine (Jiang et al, 2014;Wul et al, 2015a), and magnetic resonance imaging (Jiang et al, 2014;Shin et al, 2015). Nowadays, several kinds of magnetic nanoparticles can be synthetized, but metal oxides are preferred over pure metals nanoparticles because they are more stable to oxidation processes (Lu et al, 2007;Zhang et al, 2015a).…”
