New publication by Wolfgang Knoll, Christoph Kleber, and Roger Hasler together with colleagues from the University of Ulm, titled “A Blautia producta specific gFET-based aptasensor for quantitative monitoring of microbiome quality”.

This research highlights the development of a specific graphene field-effect transistor (gFET)-based aptasensor for monitoring key bacteria in the human microbiome, such as Blautia producta. Using aptamers — molecules engineered to bind specifically to target bacteria — the sensor allows precise, quantitative detection of bacterial cells even in complex stool samples. This innovative technology provides a fast, robust alternative to traditional sequencing methods for bacterial monitoring, with potential applications in medical diagnostics, probiotic therapy, microbiome engineering, and environmental research.
