Moreover, since the form of iron oxide used to make the droplets is magnetic, a magnetic field can be used to rotate them.

此外，由于制作这微粒的氧化铁是带有磁性的，就可以通过磁场来旋转其方向。

Furthermore, the incorporation of iron or iron oxide into such structures would provide advantages for magnetic resonance imaging (MRI).

此外，如能将铁或三氧化二铁与此类结构结合，势必将为核磁共振成像(MRI)提供更有利的条件。

Even so, he pointed out that some nanoparticles potentially serving as the basis for savvy devices of the future are already in use, including magnetic iron oxide particles used for advanced body imaging.

That would change the way the magnetic field of the iron oxide interacts with the semiconducting behaviour of the lead selenide.
