“He explained that the researchers created a mechanism able to sense TNT-like molecules frequently used in explosives at extremely low concentrations - less than 10 parts per billion.”
“This sort of technique has been looked at in the past. But this is the first time researchers have used a polyfluorene plastic laser, said Dr Turnbull. This allows the detection of much lower concent…”
“One of the selling points of plastic lasers is that they're expected to be relatively low cost, as polyfluorene is widely available, added the scientist.”
