Scientists say they have developed a quick technique for detecting liquids that could be used as explosives.
If commercialised, the new method could potentially end restrictions on liquids carried onto commercial airlines.
The light-based approach uses cheap components and can reliably identify a range of liquids in just one-fifth of a second, the German scientists say.
The work, published in the journal Superconductor Science and Technology, could have additional applications.
