UK scientists claim to have developed laser technology able to sense hidden explosives.The technology could help to detect landmines and roadside bombs and to improve airport security.The team from St Andrew’s University produced a laser by “pumping” a type of plastic called polyfluorene with photons from another light source.They found the laser reacted with vapours from explosives such as TNT.The work was published in the journal Advanced Functional Materials.
