Rethinking existing method opens new doors for cancer diagnostics

Researchers overcame limitations of current DNA sequencers by using current-tunneling measurements to measure the base sequence and quantities of DNA and microRNA simultaneously. They successfully determined the entire base sequences of four types of DNA corresponding to the let-7 microRNA, a 22-base cancer marker. The method also permits counting of DNA molecules that contain a specific base sequence.
