Nerve gas litmus test could sense airborne chemical weapons

14-Mar-2012

Nerve gases are colorless, odorless, tasteless and deadly. While today's soldiers carry masks and other protective gear, they don't have reliable ways of knowing when they need them in time. That could change, thanks to a new litmus-like paper sensor made at the University of Michigan.The paper ...
