ABSTRACT

In this fi nal chapter, we highlight several topics of current applications of magnetic particle suspensions. As already described in Chapter 1, the studies on the application in the fi eld of biomedical engineering have been growing and expanding suffi ciently to successfully lead to clinical practices which are relatively of gentle-burden to patients compared with standard surgery. Although remarkable advances in the synthesis and characterization of magnetic particles have been made for their use in the biomedical application, we focus here on the physical aspect of some of the current applications of magnetic particle suspensions in this fi eld. These research subjects will surely stimulate and challenge students and young researchers who will pioneer new fi elds of research in magnetic particles or materials in the future. In the following we address the two topics of magnetic particle hyperthermia and magnetically-propelled swimmers, where the former application makes use of the heat generated by the interaction between a magnetic particle and an alternating magnetic fi eld, and the latter application makes use of the locomotive mechanism controlled by a time-dependent external magnetic fi eld such as an alternating or rotational magnetic fi eld.
