Plastic explosives detector

Scientists in the US have developed a way to detect and differentiate between mixtures of plasticisers within plastic explosives such as Semtex and C4 to provide information for anti-terrorism activities.

The team bound a fluorescent indicator to a plasma protein, which then binds to the plasticisers. A cross-reactive array was used to reveal which plasticisers were present in the explosive mixtures.
