Peptide-Guided Hollow Gold Spheres Gather Inside Tumors, Where Light Heats Them To Kill

Peptide-Guided Hollow Gold Spheres Gather Inside Tumors, Where Light Heats Them To Kill
Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reported in the Feb. 1 issue of Clinical Cancer Research. "Active targeting of nanoparticles to tumors is the holy grail of therapeutic nanotechnology for cancer.
