New Technology Can Instantly Identify Airborne Chemicals – Down to Parts-Per-Billion

by Nanyang Technological University, SciTech Daily

Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a device that can identify a wide range of airborne gases and chemicals instantly.

The new prototype device is portable and suitable for rapid deployment by agencies to identify airborne hazards, such as from tiny gas molecules like sulfur dioxide. It can also identify larger compound molecules such as benzene, known to be harmful to human health.

It can provide real-time monitoring of air quality such as during haze outbreaks, and assist in the detection of gas leaks and industrial air pollution.

Developed by a research team led by Associate Professor Ling Xing Yi at the School of Physical and Mathematical Sciences, the new technology was reported last month in science journal ACS Nano.
