Transforming polyamide microplastics into light-emitting carbon quantum dots for UV-blocking food packaging

Plastic pollution is one of the most urgent environmental challenges of the 21st century. As larger plastic debris breaks down through mechanical, photochemical and biological processes, it forms microplastics that have been detected in water, soil, air and even the human body. Among these materials, polyamide microplastics are of particular concern because polyamide is widely used in textiles, fishing gear, packaging and engineering materials.
