Real-time microplastic detection using polarization digital holographic microscope
Summary
Researchers developed a real-time microplastic detection system using a polarization digital holographic microscope, enabling identification and characterization of MP particles in water based on their optical properties without the need for chemical staining or extensive sample preparation.
Microplastics (MPs), first identified in 1972 and defined by U.S. National Oceanic and Atmospheric Administration (NOAA) as particles smaller than 5 mm, are either primary or secondary based on their origin [1]. Plastics like polyethylene (PE), polypropylene (PP), and PET dominate packaging due to their strength and light weight. However, extensive plastic use in packaging leads to significant environmental and ocean pollution [2].
