The impact of microplastics—and how to limit exposure

To better visualize microplastics, researchers in the McBride Lab at Penn Engineering use fluorescent dyes like Nile Red, which attach to plastics and make them glow under specific light. Environmental researcher Derek Ho developed a system used in their lab called the Fluorescent Imaging Microplastic Analysis Platform, or FIMAP. It uses machine learning to detect and identify plastic particles larger than about 20 microns in complex water samples.
