"QCL application specialist Cascade Technologies has developed a way to detect explosives in airports rapidly. The alleged plot to detonate liquid explosives on transatlantic flights from the UK - uncovered last week - was a firm reminder of the growing need for airport security.
However, according to scientists at Cascade Technologies in Stirling, Scotland, there might be a sensor available within two years that could "sniff-out" explosives as routinely as existing X-ray scanners check for illicit metal." [Top Topic]
