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。

The researchers first created separate nanoparticles of two materials, lead selenide and magnetic iron oxide, with precise dimensions.

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.
