Summary
A nanowell-enhanced Raman spectroscopy substrate was fabricated using the coffee ring effect to capture and concentrate nanoplastics, enabling direct visualization and detection of single polystyrene nanoplastics as small as 200 nm in environmental samples.
Polymers
We fabricated a novel nanowell enhanced Raman spectroscopy substrate that can capture and detect nanoplastics with the aid of the coffee ring effect. Single polystyrene nanoplastics down to 200 nm can be directly visualized.
