Restrictions on liquids on commercial airlines could become a thing of the past, thanks to the research efforts by a team of scientists at the Forschunqszentrum Juelich in Germany. The team has developed a new nano electric based device that will help airport authorities in identifying potentially hazardous materials in luggages in a fraction of a second. The device which uses an optical approach rather than an electromagnetic one unlike most explosive detectors is named the Josephson junction.

The device would analyze the molecular fingerprint of the liquid in identifying it. This device will be able to check incidences like the 2006 terrorist attempt to detonate a peroxide based explosive on board a flight from Britain as hydrogen peroxide and water was almost similar.
