A new study, including Cluster Doctoral Researchers Maike Schliephake and Yan Liu and PIs Prof. Dr. Jasmin Aghassi-Hagmann and Prof. Dr. Pavel Levkin, explores the use of fluorescent metal-organic framework (MOF) thin-film arrays as surface-based sensors. They created stable, easy-to-use devices by directly patterning fluorescent dyes onto flat MOF films, overcoming the drawbacks of MOF suspensions. These arrays can track pH levels within the biological range (5–9) and detect disease-related molecules, such as dopamine. Their robust design enables multiplexed measurements and integration into lab-on-a-chip systems, creating opportunities in healthcare, environmental monitoring, and food safety.
