Mie resonances light up nanoplastics

Summary
Researchers demonstrated that Mie photonic resonances can be used as an on-chip classification method for nanoplastic particles by their optical signature. Detecting nanoplastics — the smallest and most biologically penetrant size class of plastic pollution — has been a major analytical challenge, and optical resonance methods offer a potentially rapid, low-cost detection pathway.
Photonic resonances provide an easy on-chip classification method for nanoplastic particles.
