Carbon nanotube sensor array detects VOCs below 100 ppb with high selectivity, enabling electronic nose applications for precise chemical vapor identification. (Nanowerk News) A team of researchers at ...

(Nanowerk News) Environmental sensors are a step closer to simultaneously sniffing out multiple gases that could indicate disease or pollution, thanks to a Penn State collaboration. Huanyu “Larry” ...

Not all poisonous gases have a smell or a color. But a tiny grid of pastel- and candy-colored squares that effectively “sniffs” out hazardous chemicals in the air such as chlorosarin — a highly toxic ...

Environmental sensors are a step closer to simultaneously sniffing out multiple gases that could indicate disease or pollution. Researchers combined laser writing and responsive sensor technologies to ...
