'Nanoshells' simultaneously detect and destroy cancerous cells

Researchers at Rice University in Texas have developed a new approach to fighting cancer, based on nanoscale particles that can both detect and destroy cancerous cells. The report appears in the April 13 issue of the American Chemical Society's journal Nano Letters. ACS is the world's largest scientific society.

Current molecular imaging approaches only detect the cancer but don't offer a method of treatment, according to the study's lead authors, Rebekah Drezek, Ph.D., and Jennifer West, Ph.D., both professors in the Department of Bioengineering at Rice.

"You can look for a molecular marker that may indicate a significant clinical problem, but you can't do anything about it [just through imaging]," says Drezek. "We don't want to simply find the cancerous cells. We would like to locate the cells, be able to make a rational choice about whether they need to be destroyed and, if so, proceed immediately to treatment."
