The Future: Dog on a Chip

Nov 24 2003, 11:52pm EST | by Luigi Lugmayr

Reuters carries a story about a new advanced electronic sensor system that supposedly can replace dogs in drug search in the near future.

"We took the road less traveled and went in the direction of fusing biotechnology and microelectronics," said William Hunt, a professor of electrical and computer engineering who led the study.

The dog-on-a-chip works with antibodies by looking at their molecular structure, Hunt said. In this case the researchers tested cocaine antibodies, which change in structure and mass if they come into contact with cocaine molecules.
On the device, these changes trigger an electronic alert through a laptop, Hunt said, but researchers hope to make the whole package portable and battery-operated, either as a hand-held unit or as a device monitoring a particular area.
