Microfluidics-based electrophoretic capture and Raman analysis of micro/nanoplastics

Capturing, enriching and detecting nanoplastics in water based on optical manipulation, surface-enhanced Raman scattering and microfluidics

AI summary · Read the abstract

Scientists built an optical manipulation and surface-enhanced Raman scattering system using gold nanoparticle stacks to simultaneously capture, enrich, and detect nanoplastics in natural water at concentrations as low as 150 ng/L for polystyrene, successfully quantifying nanoplastics across river, mariculture, and beach water samples. The technique fills a critical measurement gap for nanoplastics, enabling reliable concentration monitoring in environments where these particles are otherwise nearly impossible to detect and quantify.
