Abstract

Magnetic nanoparticles have attracted great interest over the last decades due to their novel magnetic properties, such as superparamagnetism, that arises when the size of the material is reduced to the nanoscale. Furthermore, they can be manipulated by external elds and their size is comparable to biological entities, which makes them very interesting for biomedical applications. The development of synthesis methods and surface chemistry have made possible their application in several dierent fields, both technological and biomedical. In particular, iron oxide nanoparticles, such as magnetite Fe3O4 or maghemite Fe2O3, are one of the most used magnetic nanoparticles in biomedical application. On the other hand, glass-coated magnetic amorphous microwires exhibit excellent soft magnetic properties. Their properties and magnetic structure can be easily manipulated, which makes these materials very attractive for several application, such as their use in temperature or pressure sensors..
