Microchip IDs cancerous tumors in less than one hour
Scientists say they have developed a microchip that can be attached to a smart phone and diagnose cancerous tumors within an hour, from the patient's bedside. The so-called microNMR chip, which uses magnetic nanoparticles to measure proteins and other chemical compounds in tumors, requires only tiny amounts of tissue to make a diagnosis, researchers said. Instead of more invasive methods, the biopsy can be done with fine needle aspiration, which withdraws cells from suspicious lesions. "We tried to determine a molecular fingerprint, if you will," said study co-author Jered B. Haun, a postdoctoral researcher at Massachusetts General Hospital in Boston. "It was a nice surprise just how well it worked with all the protein markers. One of our big goals was not only to be able to tell patients they have cancer as accurately as possible, but as quickly as possible."
