New graphene-based sensor design could improve food safety

In the U.S., more than 100 food recalls were issued in 2017 because of contamination from harmful bacteria such as Listeria, Salmonella or E. coli. A new sensor design could one day make it easier to detect pathogens in ...

Photonic radiation sensors survive huge doses undamaged

Researchers at the National Institute of Standards and Technology (NIST) have published landmark test results that suggest a promising class of sensors can be used in high-radiation environments and to advance important medical, ...

Paper-based lateral flow device to detect uranium in groundwater

The presence of uranium in groundwater can lead to severe health problems, from renal failure to cancer. Standard methods to detect uranium involve time-consuming processes and expensive, non-portable equipment. Measurements ...

'Majority rules' when looking for earthquakes, explosions

A dormant volcano in Antarctica helped researchers at Sandia National Laboratories improve sensor data readings to better detect earthquakes and explosions and tune out everyday sounds such as traffic and footsteps.

Machine learning helps improving photonic applications

Photonic nanostructures can be used for many applications besides solar cells—for example, optical sensors for cancer markers or other biomolecules. A team at HZB using computer simulations and machine learning has now ...
