Nanodevice Defeats Drug Resistance

Researchers from MIT have developed a new nanodevice that can defeat drug resistance by turning off the drug resistant gene and then releasing cancer drugs against the disarmed tumors. Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice developed by MIT researchers […]
