Nanotechnology-enabled analytical tools for Microplastics and nanoplastics in aquatic ecosystems

AI summary · Read the abstract

Tiny plastic particles in our water, some smaller than a virus, have been hard to detect with older lab tools, making it tough to know how much is really out there or how it might affect us. This review rounds up new nanotech-based detection methods (using gold nanoparticles, light-scattering sensors, and AI) that can spot these nanoplastics at incredibly low levels, faster and with less environmental impact than traditional testing. Better detection tools like these are a key first step toward understanding plastic pollution's health risks and building policies to protect our water supplies.
