Fluorescent test strip detects deadly phosgene gas

Chinese scientists have improved the sensitivity of test strips for phosgene gas by using a different fluorophore.

Phosgene gas reacts with lung proteins, disrupting the blood–air barrier and suffocating victims. Although deadly, many chemical plants require phosgene to synthesise products such as pharmaceuticals and pesticides. But accidental leaks are a risk. In 2016, for example, a leak at Gujarat Narmada Valley Fertilizers and Chemicals in India killed four workers and affected nine others.
