A new way of detecting chemical weapons: thin-film materials change color in response to chemical warfare agents.

According to a report in the scientific journal ACS Macro Letters, scientists are reporting new progress toward thin-film materials that could rapidly change colors in the presence of CWAs — an advance that could help save lives and hold aggressors accountable.
