Nanotube transistors detect gene mutations

University of Pittsburgh and Nanomix researchers have used carbon nanotubes network field-effect transistors as biodetectors of mutations in genes causing hereditary diseases.
The method is an “important step toward low-cost, low-complexity, highly sensitive and accurate molecular diagnostics,” the authors say.
