Innovative sensor specifically and precisely detects molecules

Researchers of Karlsruhe Institute of Technology (KIT) and Technical University of Darmstadt have developed a novel sensor for gas molecules by combining a graphene transistor with a customized metal-organic coating. The ...

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 ...

Ultra-fast, ultra-sensitive PtSe2 gas sensors

Researchers from Trinity College Dublin, Ireland have shown that PtSe2, a little-studied transition metal dichalcogenide has potential for a variety of uses. In particular, PtSe2 is an excellent high performance gas sensor, ...

Novel technique used to study graphene's response to air

An international team of scientists led by the National Physical Laboratory (NPL) has performed novel measurements of graphene's electrical response to synthetic air, exposing a distinct knowledge gap that needs to be bridged ...

Thumb-sized device quickly 'sniffs out' bad breath

No one wants bad breath—not when visiting friends and family, at a job interview, and especially not on a first date. Smelly breath can make things awkward, but it also is a natural warning sign, indicating that serious ...

Twist-and-glow molecules aid rapid gas detection

In an emergency such as a factory fire, ascertaining which gases are present in the air is critical to preventing or minimizing poisoning (Fig. 1). This requires gas sensors that react quickly and provide a visual signal. ...
