Microscopic robots might be a common sci-fi but they're theme, increasingly finding their way into real-life applications.
The most recent application comes from a team of researchers in Canada who are using tiny bots, in conjunction with magnetic resonance imaging (MRI) machines, to treat liver cancer. As the robots are made of iron-oxide nanoparticles, they can be guided by an external magnetic field in this case, the field generated by the MRI machine - to theoretically provide targeted medical treatment.
