3D-printed dog’s nose sniffs out why canines are excellent chemical analysers
By Tushna Commissariat
After a long trip in the US – attending the APS March meeting and visiting both the Maryland campus of the National Institute for Standards and Technology, as well as the Brookhaven National Laboratory in New York – I finally made my way back home yesterday. As I flew out of New York, I was reminded of my visit to NIST’s Surface and Trace Chemical Analysis Group, where researchers develop a variety of ways to detect contraband substances at airports and other public locations. While the team looks into a variety of ways to detect trace residues of banned substances such as drugs or explosives that may be found on people or objects – from mass spectroscopy to thermal desorption to vapour-sampling – my favourite was their canine research that led them to create a 3D-printed dog’s nose!
