Despite the differences that exist at this point about the definition of microplastic particles, if considering only their sizes, elements smaller than 5 mm in diameter with no lower limit are considered. They constitute a wide range of chemically complex materials, often with additives and fillers influencing properties such as color, density, durability. This diversity in properties and wide particle size range means that as a group of analytes, they are challenging to efficiently detect and identify in complex environmental matrices, especially when nanometric range dimensions are involved.
This project proposal aims at developing a new laser-based device for detection of microplastics in water.
Its scope derives from the need to find a way for faster and accurate detection of microplastic particles in fluids with a limited number of measurements, easy processing and sampling. For this, we will develop a subsystem capable to detect microplastics in water droplets using enhanced Raman scattering spectroscopy. This will be joint with another subsystem based on optofluidic measurements at the surface of an air bubble generated in polluted bulk water sample performed by real time surface and interfacial tension measurements. The interaction between microdroplets and bubbles with laser beams belongs to a rather new field of multidisciplinary research, the optofluidics, which deals with the interaction of optical radiation with fluid systems. The combination of the enhanced sensitivity of the Raman scattering technique obtained using very small samples (microdroplets) with the latest developments in the topics of microfluidics and optical spectroscopy may constitute an advance in the field of online monitoring of water pollutants.
