Magnetic nanomotors with integrated theranostic capabilities

Nanowerk.com - 5 января, 2018 - 12:05
The role of artificial nanomotors integrated with therapeutic capabilities is a very promising field for clinical applications of medical nanotechnology. Researchers now have demonstrated the intelligent design of nanomotors with a single coating of ferrite, which act as a spacer layer as well as providing therapeutic potential by magnetic hyperthermia. These motors can be remotely maneuvered. The team also tackled the problem of magnetic agglomeration associated with ferromagnetic nanomotors, which limits their biomedical application.
