To warn of chemical attacks and help save lives, it’s vital to quickly determine if even trace levels of potentially deadly chemicals - such as the nerve gas sarin and other odorless, colorless agents - are present.

A paper describing the system has been published in the Optical Society’s (OSA) journal, Optics Letters.
