ClearNarrow-Window Cathodic Electrochemiluminescence from Laser-Engineered Graphitic Carbon Nitride: A Next-Generation Emitter for Microplastics Biosensing
Scientists developed a new way to detect tiny plastic particles (called microplastics) in seawater that is more accurate than current methods. The new technique can find extremely small amounts of plastic pollution - as little as 0.2 billionths of a gram per milliliter of water. This matters because microplastics are everywhere in our oceans and food chain, and better detection methods help us understand and monitor this growing pollution problem that could affect human health.
