Dogs and cats, with their highly developed sense of smell, have been detecting cancer or predicting epileptic seizures for some years now..

But what if we could digitize that sense and put it into a microchip, allowing us to create a breathalyzer for diseases?

For Dr. Andrew Koehl, the inventor of the microchip spectrometer technology at the heart of this “digital nose”, the technology that will allow us to do just that is already here, reports CNN.

“We can detect down to parts per billion levels,” Koehl says. “To give you an analogy that’s equivalent to one drop in an Olympic size swimming pool.”
