At our group, led by Dr. Frank Rosenau, we develop innovative diagnostic tools and antimicrobial strategies using aptamers and peptides. Our research focuses on creating aptamers to detect key gut bacteria, pathogens on the WHO priority watchlist, and a wide range of small molecules and biological targets. We are also developing graphene-based field-effect transistor (gFET) biosensors, which use aptamers for highly sensitive and precise biomolecule and whole cell detection. By combining aptamer technology with antimicrobial peptides, we aim to improve disease monitoring, diagnostics, and targeted treatments for infections.
