Trusty sniffer dogs that are used to detect drugs, explosives and missing people could soon be replaced by a ‘robo-nose’.
Trained dogs are taught to use their sensitive sense of smell to detect the presence of certain chemicals and scientists have successfully recreated a robotic alternative.
Researchers used genes from the nose of mice to develop the olfactory organ which they hope will one day replace the dogs.
Detection dogs are invaluable to security are expensive to train and often get tired.
A robotic alternative, being developed by researchers at the Duke School of Medicine in North Carolina, involves a prototype that used odour receptors from mice.
