Nanotubes sniff out cancer agents in living cells

A multidisciplinary team at the Massachusetts Institute of Technology (MIT) has developed carbon nanotubes that can be used as sensors for cancer drugs and other DNA-damaging agents inside living cells. The sensors, made of carbon nanotubes wrapped in DNA, can detect chemotherapy drugs such as cisplatin as well as environmental toxins and free radicals that damage DNA.

Artificial antibody delivers nanoparticles to tumors

Antibodies that target epidermal growth factor receptor (EGFR) have proven themselves as potent anticancer drugs. Now, a team of investigators led by Shuming Nie, Ph.D., and Lily Yang, Ph.D., both at the Emory University School of Medicine and members of the Emory-Georgia Tech Nanotechnology Center for Personalized and Predictive Oncology, is aiming to capitalize on this targeting ability, using a modified anti-EGFR antibody to delivery nanoparticles into tumor cells.
