Although there are now a number of skin-worn sensors which identify metabolites in sweat, the technology is limited in what it can detect, plus the sensors often aren't reusable. A new one, however, ...

A new light-based sensor can spot incredibly tiny amounts of cancer biomarkers in blood, raising the possibility of earlier and simpler cancer detection. The technology merges DNA nanotechnology, ...

A new sticker changes in shape inside the body, enabling standard ultrasound technology to detect leaks for earlier detection and intervention. John Rogers, Louis Simpson and Kimberly Querrey ...

Researchers have developed a highly sensitive light-based sensor that can detect extremely low concentrations of cancer ...

Gastrointestinal surgeries carry risk of fluid leaks, a potentially life-threatening complication. But no existing methods can reliably and non-invasively detect these leaks. To address this unmet ...
