Breakthrough in cancer tests

Jack Andraka, a high school student in Maryland has invented a new test for cancer of the liver, breast, or pancreas while they are still in early stage. It’s a blood test that takes seconds. It takes 1/168 of the time, is 400 times more sensitives, and it costs 1/26,000 as much. It costs 3¢ and takes five minutes.

The test uses single-walled carbon nanotubes to detect mesothelin, a protein that is overproduced by certain cancers, including mesothelioma and ovarian and pancreatic adenocarcinoma. Jack sent 200 e-mails about his proposed experimental procedure and collected 199 rejections. He found one lab where he test his idea.

Jack credits the Internet for online journals–he was reading in biology class about nanotubes as biosensors–and search engines that let him learn enough to do this.
