Identifying pathogenic bacteria in just seconds

Field testing of a portable pathogenic bacteria alert and identification system began a few days ago in the South of France. The system, developed by Leti and List combines lensless imaging, Raman spectrometry, and supervised classification algorithms. The system, named Bacram, was developed under the counter-bioterrorism research program of the French government’s CBRND* policy. It is capable of generating a response in just minutes, with no need for cultures or markers. It is sensitive enough to detect an individual bacteria in a sample, even if contaminated.

The excellent detection results achieved in laboratory conditions have already garnered interest from a potential manufacturer, who is anxiously awaiting the field testing results.
