NEW YORK (GenomeWeb) – A group led by University of California, San Diego researchers has developed an electronic DNA biosensor tool that it plans to apply for highly sensitive point-of-care SNP detection and infectious disease diagnostics.

Integrating DNA nanotweezer-based nucleic acid-sensing probes and a graphene field effect transistor (FET) chip, the real-time platform can be used to identify SNPs of interest, send data to personal electronic devices, and even potentially be integrated into implantable biosensors.
