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 tiny laser and a corresponding light detector has been developed in one production process, on a single chip. The light is transported from the laser to the detector on a specially designed ...

Optical biosensors based on surface-plasmon resonance are an important tool used for studying how various biomolecules interact with each other - for example antibodies in the immune system. With his ...

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 ...

The wearable sensor market is growing at an annual compound rate of 17.8%. However, sensors have challenges, particularly in terms of miniaturization and power consumption. Several key parameters are ...

Diagnosing some diseases could be as easy as breathing into a tube. MIT engineers have developed a test to detect ...

MOFFETT FIELD, Calif. — NASA recently tested the first nanotechnology-based electronic device to fly in space. The test showed that the “nanosensor” could monitor trace gases inside a spaceship. This ...

Recently an ad on YouTube about an acoustic light sensor/switch module piqued my interest. Out of curiosity, I contacted the online vendor and bought a pair. Named MR-SK50A, the module is less popular ...
