Molecularly Imprinted Photoactive Microswimmers for PFAS Capture and Detection

Per- and polyfluoroalkyl substances (PFAS), commonly known as forever chemicals, are persistent organic pollutants of global environmental concern with serious health risks. Their extensive industrial use and toxic effects have led to the implementation of stringent regulations worldwide, highlighting the urgent need for more efficient and sensitive PFAS detection technologies. Current detection methods are often inefficient, time-consuming, and lack the sensitivity required for trace-level analysis and accurate identification. This project, PhotoSERS, aims to develop an innovative technology based on light-driven microswimmers capable of both capturing and detecting PFAS in water. These microscale devices combine active motion with selective molecular recognition. By integrating advanced spectroscopic detection and portable instrumentation, the system aims to enable real-time, sensitive, and reproducible monitoring of these contaminants. Collaboration with industrial partners will ensure the industrial relevance of our technology by providing critical feedback on performance requirements, and supporting validation in real operational settings, ultimately accelerating its path to commercialization. Therefore, this innovative portable microswimmer-based device could contribute significantly to water monitoring technologies and environmental protection efforts by providing an efficient, field-deployable solution for PFAS capture and detection.
