Microplastic particles in water are an increasing problem for the environment. A smart silicon wafer-based filter system that makes it faster and easier to measure water pollution was developed by the Fraunhofer Center for Silicon Photovoltaics CSP together with partners in the RUSEKU research project.
At present, there is a lack of methods for efficient and reliable sampling for the systematic investigation of sources, pathways and effects on the environment. In particular, selective filters for rapid microplastic analysis are needed.
The Fraunhofer Center for Silicon Photovoltaics CSP in cooperation with SmartMembranes GmbH offers smart filter systems for rapid microplastic analysis based on silicon as well as alternative materials (Al2O3, glass). The filters (pat. pend.) are part of a special cascade filter system and a central component for a future standardized and uncomplicated sample collection procedure. In addition, the "Smart Sampling" filters are suitable for subsequent microplastic rapid analysis to determine particle sizes and plastic types.
