These tiny “nanobarcodes” fluoresce under ultraviolet light in a combination of colors that can then be read by a computer scanner or observed with a fluorescent light microscope.
The Cornell University research group behind the project likens the technology to a supermarket checkout computer, capable of identifying thousands of different items by scanning barcodes.

In an effort to limit acute gastroenteritis, or food poisoning, the second most prevalent household illness, Cornell professors from the department of Population Medicine and Diagnostic Sciences have joined a research team which aims to identify the origin and transmission of pathogens that cause food-related illnesses.

The research team is comprised of over 50 experts from 18 different campuses across the country.
