Scientists developed a new method to detect tiny plastic particles (called microplastics) in drinking water using special fluorescent dots that dim when they encounter plastic pollution. The technique works best at finding very small plastic pieces—smaller than the width of a human hair—which are hardest to detect but potentially most dangerous since they can get into our bodies more easily. This could help monitor plastic contamination in tap water and other water sources we use daily, giving us better information about our exposure to these harmful particles.
