Abstract
Microplastic pollution in aquatic systems poses ecological and health risks. However, current detection methods (e.g., FTIR, Raman spectroscopy) are time-consuming, costly, require skilled personnel and lack field applicability. We present a dual-channel fluorescence-based optical sensor for rapid detection and classification of microplastics dispersed in water. The detection is accomplished by exploiting the affinity of fluorescent solvatochromic dye DANS with plastic microparticles. A dual-channel pulse inten-sity spectral analysis of fluorescence emission enables the identification of at least three different mi-croplastics: polypropylene (PP), polystyrene (PS) and polyethylene terephthalate (PET).
