Noncytotoxic ferromagnetic FePt nanomotors possess hard magnetic properties that rival NdFeB micromagnets and enable active gene delivery. In article 2001114, Maximiliano G. Gutierrez, Peer Fischer, and co‐workers describe their fabrication and material characterization, and show that FePt is promising for microrobotics and biomedical applications.
The application of nanoparticles for drug or gene delivery promises benefits in the form of single‐cell‐specific therapeutic and diagnostic capabilities. Many methods of cell transfection rely on unspecific means to increase the transport of genetic material into cells. Targeted transport is in principle possible with magnetically propelled micromotors, which allow responsive nanoscale actuation and...
