Microrobots roll against blood flow to deliver drugs

Tiny microrobots could travel the bloodstream to one day deliver cancer drugs to hard-to-reach tumors deep inside the body. ↓↓More info and references below↓↓ With the help of a magnetic field, these two-faced particles might one day navigate our circulatory system to deliver treatments to tumors. The microrollers are coated on one side with magnetic materials and on the other with antibodies specific to cancer cells. These antibodies would help the particles selectively bind to tumors in the body, where they could release their payload. This targeted approach could minimize exposure of healthy cells to cancer drugs, reducing side effects.
