Chinese scientists have built a hand-held device to detect early signs of lung cancer from just a drop of blood, a ...

When we think about highly sensitive medical testing, we often imagine a hospital laboratory filled with large instruments, trained technicians, and carefully controlled conditions. This is especially ...

Scientists have developed a new kind of wearable sensor that can detect signs of eye disease—without drawing blood or using expensive lab equipment. Instead, it’s a soft, non-invasive patch placed ...

(Nanowerk Spotlight) Eye tracking holds immense potential for enabling intuitive human-computer interaction, yet existing approaches remain cumbersome. Camera-based systems require complex image ...

Researchers have developed a highly sensitive light-based sensor that can detect extremely low concentrations of cancer biomarkers in the blood. The new technology could one day make it possible to ...

Quantum computers are still a work in progress but quantum sensors are already in use at hospitals, laboratories and by ...
