Abstract
None:
We present a fast, eco-friendly method for detecting polyethylene microplastics (<10 μm) in wastewater effluent using curcumin as a natural fluorescent dye. Curcumin-stained particles exhibited strong green fluorescence and electrophoretic capture in a microfluidic device, demonstrating a sustainable alternative to synthetic dyes for environmental microplastic detection.
