A field effect transistor (FET) is a carrier device with three terminals: source, drain, and gate. In FETs, an electric field can be applied at the terminal of the gate, modifying the conductive ...

Wearable biosensors typically consist of a recognition region that detects the target signal, a transducer that converts that signal into a measurable parameter, and an electronic processor that ...

Dr. Ho Sang Jung and his research team from the Advanced Bio and Healthcare Materials Research Division at the Korea Institute of Materials Science (KIMS) have developed an optical biosensor capable ...

Can accurately analyze sweat to provide real-time hydration guidelines. Uses a non-invasive patch to adhere the sensor to your arm. Takes fitness devices to a new level. Nix has so far provided thin ...

The biosensor uses "capture probes" called aptamers, which are single strands of DNA that bind to virus proteins, flagging them. The team's big challenge was finding a way to get these aptamers to ...

Cornell researchers have developed a powerful new biosensor that reveals, in unprecedented detail, how and where kinases—enzymes that control nearly all cellular processes—turn on and off inside ...

Researchers report successful results from a hand-held breast cancer screening device that can detect breast cancer biomarkers from a tiny sample of saliva. Their design uses common components, such ...
