Detection of microplastics from water is crucial for various reasons, such as food safety monitoring, monitoring of the fate and transport of microplastics, and development of preventive measures for their occurrence. Currently, microplastics are detected by isolating them using filtration, separation by centrifugation, or membrane filtration, subsequently followed by analysis using well-established analytical methods, such as Raman spectroscopy. However, due to their variability in shape, color, size, and density, isolation using the conventional methods mentioned above is cumbersome and time-consuming. In this work, we show a surfacenanodroplet-decorated microfluidic device for isolation and analysis of small microplastics (diameter of 10 μm) from water. Surface nanodroplets are able to capture nearby microplastics as water flows through the microfluidic device. Using a model microplastic solution, we show that microplastics of various sizes and types can be captured and visualized by using optical and fluorescence microscopy. More importantly, as the surface nanodroplets are pinned on the microfluidic channel, the captured microplastics can also be analyzed using a Raman spectroscope, which enables both physical (i.e., size and shape) and chemical (i.e., type) characterization of microplastics at a single-particle level. The technique shown here can be used as a simple, fast, and economical detection method for small microplastics.

“…These solvents have been characterized in previous studies and their synthesis in our laboratory was according to the agenda of previous studies. For this purpose, nine DESs including DES-I (MTOAC: n -butanol, 1:3) [ 14 ], DES-II ( l -menthol:EG, 1:1) [ 15 ], DES-III ( l -menthol:SA, 4:1) [ 22 ], DES-IV ( l -menthol:CSA, 5:1) [ 23 ], DES-V ( l -menthol:phenol, 1:1) [ 24 ], DES-VI ([DMIM]Cl:1-undecanol, 1:2) [ 25 ], DES-VII ([DMIM]Cl: n -butanoic acid, 1:2) [ 18 ], DES-VIII (TBAC: p -aminophenol, 1:2) [ 26 ] and DES-IX (thymol:decanoic acid, 1:2) [ 27 ] were synthesized and investigated. The DESs features, along with their references, are presented in Table 1 .…”
