Gentle touch of nanochip can detect oral cancer
Researchers at Rice University have found that a simple swipe of a diagnostic biochip is 93 percent "specific" in detecting which of 52 patients being studied had malignant, as well as premalignant, lesions--results they say compare well with traditional (but more invasive) screening.
"One of the key discoveries in this paper is to show that the miniaturized, noninvasive approach produces about the same result as the pathologists do," says John McDevitt, the Brown-Wiess Professor of Chemistry and Bioengineering at Rice, in a news release this week.
McDevitt's lab developed the novel nano-biochip technology at the … Read more
