ClearFabrication and characterization of (fluorescent) model nanoplastics for polymer specific detection
This study developed and characterized fluorescent model nanoplastics that can be tracked and identified by polymer type, providing standardized reference particles for laboratory research.

Irregularly Shaped True-To-Life Microplastics with Embedded Optical Labels
Scientists have created fake plastic particles that look and act like the real microplastics found in our environment, but with special glowing labels so researchers can track them.
