ESR4: Detection and characterisation of micro- and nanoplastics in beverages and food.


Overview: The ESR at KTH will develop filter based sample preparation strategy to separate micro- and nanoplastics from water, beverage (beer) and foodstuff (salt and honey). Two parallel routes will be investigated, one approach will be a stand-alone sample preparation module using filters with various pore sizes, and a second approach will use centrifugal microfluidics for integrated sample preparation. In collaboration with ESR3, the first stand-alone approach will be integrated and/or combined with inertial microfluidics to deliver different sized plastics for downstream analysis.

ESR9: Multispectral imaging flow cytometry for assessment of microplastic particles


Overview: The ESR will develop and apply a multispectral imaging flow cytometry (mIFC) approach to assess microplastic particles in the size range between 2 and 40 µm based on their geometrical and colorimetric properties. ´Different affinities of plastic materials to dye molecules will be utilized to discriminate between microplastic materials. The number and size of microplastic particles will be detected as well to determine their content. Combined with appropriate separation and enrichment techniques mIFC can assess microplastics from various matrices such as seawater, sediments, food, drinks, plants and tissues.

ESR10: High throughput Raman spectroscopy for analysis of microplastic particles


Overview: The ESR will develop a high-throughput Raman microspectrometer with laser line excitation for analysis of microplastic particles on a substrate or in continuous flow. The laser excitation wavelength, spectrometer and detector will be selected that are most appropriate for Raman-based detection of coloured and non-coloured microplastics. Automation will include particle localization on the substrate before acquisition of Raman spectra. Acquisition of microplastic particles in a microfluidic chip will be synchronized with an image-based detection. A database of microplastics will be compiled and chemometric data analysis will classify the microplastic particles. Commercial databases will be tested as alternative approaches.

ESR3: Detection and characterisation of micro- and nanoplastics in beverages and food


Overview: The ESR at KTH will develop size based microfluidic continuous particle separation methods, based on inertial focusing. Inertial microfluidics is a passive, label-free separation method and both straight channel and spiral microfluidic devices with unique geometry to continuously focus and separate particles at a volumetric flow rates not reported in other microscale systems will be studied. In this project, inertial microfluidics will be applied for high throughput enrichment of micro and nanoplastics, primarily from water sample and then also in other matrices such as beverages (e.g. beer).
