A breath test for early-stage Parkinson's

Symptoms of Parkinson's disease include tremor, loss of smell and neuropsychiatric problems. However, many people aren't diagnosed until their disease is well-advanced, which could limit their treatment options. Now, researchers ...

New nerve gas detector built with legos and a smartphone

Researchers at The University of Texas at Austin have designed a way to sense dangerous chemicals using, in part, a simple rig consisting of a smartphone and a box made from Lego bricks, which could help first responders ...

Portable device to sniff out trapped humans

The first step after buildings collapse from an earthquake, bombing or other disaster is to rescue people who could be trapped in the rubble. But finding entrapped humans among the ruins can be challenging. Scientists now ...

Rapid detection of toxic compounds

NUS chemists have developed highly selective and sensitive sensors based on molecularly imprinted polymers (MIPs) for the rapid onsite detection of toxic agents.

MXene material could improve sensors that sniff

Sensors that sniff out chemicals in the air to warn us about everything from fires to carbon monoxide to drunk drivers to explosive devices hidden in luggage have improved so much that they can even detect diseases on a person's ...

Researchers greenlight gas detection at room temperature

Russian researchers have developed a mechanism for detecting molecular hydrogen using green light to illuminate a nanocrystalline composite sensor based on zinc and indium oxides. This enables a gas sensor operating at room ...

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 ...

New med-tech zinc sensor developed

A new zinc sensor has been developed by researchers, which will allow for a deeper understanding of the dynamic roles that metal ions play in regulating health and disease in the living body.
