3D-Printed Microbots Deliver Drugs by Navigating Arteries and Veins

The titanium microbots could one day provide a minimally invasive method for delivering therapies in humans.

The microrobots with fluorescent HeLa cells were injected into the left dorsum of the nude mice. After four weeks of cultivation, an area with increased fluorescence intensity was observed at the left dorsum of the mouse (indicated by the white arrow), indicating that the tumor was due to the release of HeLa cells from the microrobots. | Li et al., Sci.
