Ultrafast DNA Nanosensor

Filed under: news — seniorgeek @ 8:26 pm

“A portable instrument based on an ultrasensitive nanoscale sensor could detect bacteria in minutes, helping to catch infectious diseases early and prevent their spread. The simple, low-cost device should be available within three years, says Benjamin Miller, professor of dermatology and biomedical engineering at the University of Rochester Medical Center, and codeveloper of the sensor.”
