Being able to quickly confirm the presence of infectious bacteria in a patient’s bloodstream, and then identifying the specific species and strain, can make the difference between life and death for that patient. While traditional detection and identification methods are fairly accurate, they can also take too long to perform. A chemist from the University of Illinois, however, has developed an inexpensive new system that is much quicker – and it works by sniffing out the harmful bacteria.
