New Nanodevice Defeats Drug Resistance: Tiny Particles Embedded in Gel Can Turn Off Drug-Resistant Genes, Then Release Cancer Drugs

March 3, 2015

(Nanotechnology Now) – 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 can help overcome that by first blocking the gene that confers drug resistance, then launching a new chemotherapy attack against the disarmed tumors.
