Laser-Activated Microrobots Deliver Drug Therapy
Microrobots developed by Caltech’s Lihong Wang and Wei Gao may provide a new way of treating cancers in the digestive tract. They travel through the stomach and intestines carrying medication until they are activated by a pulse of laser light. When activated, they travel forward on a jet of tiny bubbles until they embed themselves into nearby tissue, where they slowly release their medicine.
