Tracking of diseases in the body is important to be able to assess outcomes and increase therapeutic efficacy in patients. Magnetic core–shell iron nanowires have now been used to create a new surveillance technique of live cells in the body. The nanowires are nontoxic and act as contrast agents that can be visualized by MRI, highlighting the location of cells they have been implanted into. The iron nanowires could be used for a wide range of applications, including studying cancer and monitoring stem cell therapies.
