Microrobots Activated by Laser Pulses Show Promise For Treating Tumors


MedE Professors Wei Gao and Lihong Wang are working on microrobots that can deliver drugs to specific spots inside the body while being monitored and controlled from outside the body. "These micromotors can penetrate the mucus of the digestive tract and stay there for a long time. This improves medicine delivery," Professor Gao says. "But because they're made of magnesium, they're biocompatible and biodegradable." [Caltech story]

The Science of Sweat


Wei Gao, Assistant Professor of Medical Engineering, is interested in the future of personalized and precision medicine, and is engineering the next generation of wearable health monitors and nanomachines that could enable rapid and hyper-localized drug delivery and surgery. The sweatband health tracker he is developing is capable of studying health at a molecular level. By analyzing an individual’s sweat, the device can monitor dehydration levels as well as blood glucose levels in real time. [Caltech interview]
