"WELSH scientists have developed a sensor they call a nanodog which is capable of "sniffing" out microscopic low levels of explosives. It is hoped the technology will be used in the fight against terrorism, with airports and governments already showing an interest. The nanodog was developed by a team from the University of Wales, Bangor's school of chemistry, led by Professor Maher Kalaji."
