Gold Nanorods Hitch Ride on Immune Cells that Target Breast Tumors

One of the challenges in treating cancer, whether using nanotechnology or not, is that tumors can often be inaccessible to the therapies designed to kill them. Mostafa El-Sayed, of the Georgia Institute of Technology, and his colleagues are attempting to overcome this obstacle by designing drug-loaded gold nanorods that attract the attention of tumor-associated immune cells known as macrophages. The researchers believe that these macrophages will then deliver the nanorods to the tumors, crossing the normally impermeable blood-brain barrier to do so.

Dr. El-Sayed, who is a co-principal investigator of a Cancer Nanotechnology Platform Partnership held jointly by Georgia Tech and Emory University, and his colleagues have synthesized gold nanorods that target tumor-associated macrophages.
