Researchers from the University of California, San Francisco and Georgia Institute of Technology have found a new way to kill cancer cells. Building on their previous work that used gold nanoparticles to detect cancer, they now are heating the particles and using them as agents to destroy malignant cells.
The researchers are a father and son, working together on opposite coasts. Their study findings are reported in the on-line edition of the journal Cancer Letters, found at Sciencedirect.com (quicksearch: El-Sayed nanoparticles).
"In an earlier study we showed how gold nanoparticles could be bound to malignant cells, making cancer detection easier. Now we have examined how the particles' ability to absorb light helps kill those cancer cells," said principal author Ivan El-Sayed, MD
, assistant professor of otolaryngology at UCSF Medical Center.
Ivan conducted the study with his father, Mostafa El-Sayed, PhD, director of the Laser Dynamics Laboratory and chemistry professor at Georgia Tech.
