Biosensor may provide better cancer diagnosis

Lawrence Livermore National Laboratory (LLNL) researchers have developed a new biological sensor that could help clinicians better diagnose cancer and epilepsy.

Measuring forces of living cells and microorganisms

Forces exerted by a living cell or a microorganism are tiny, often no larger than a few nanonewtons. For comparison, one nanonewton is the weight of one part in a billion of a typical chocolate bar. Yet, for biological cells ...

When roots crack and worms crunch

Roots can be "listened to" while growing – and worms when burrowing. Researchers from ETH Zurich and the French National Institute for Agricultural Research present a new method for soil analysis.

A fashionable chemical and biological threat detector-on-a-ring

Wearable sensors are revolutionizing the tech-world, capable of tracking processes in the body, such as heart rates. They're even becoming fashionable, with many of them sporting sleek, stylish designs. But wearable sensors ...

Advanced molybdenum selenide near infrared phototransistors

Optical sensors operating in the near infrared (NIR) are important for applications in imaging, photodetectors, and biological sensors. Notably, recent reports on the synthesis of high quality, large areas of graphene has ...
