Description

The Molecular Tools for Biosignature Tracking group (711 HPW/RHXB) is focused on engineering molecular tools to create systems that sense and respond to different types of analytes with a focus on biomarkers of stress, fatigue, and cognitive performance. Our technical work integrates the selection and design of biorecognition elements (BREs) that can bind different types of analytes, from small molecules to proteins, and their integration in different sensor platforms. We are particularly interested in nucleic acid (NAs)-based BREs due to their high affinity and selectivity and the ability to engineer different types of reporter signals upon analyte binding. This versatility provides the potential to create technological solutions to improve the Airman’s performance, from biomarker changes tracking in biofluids during in-the-field activities to neurochemicals tracking in the brain and peripheral tissue. We combined experimental and modelling tools to understand and improve BRE performance in different environments, including the interface of nanomaterials, in cellular systems and within larger multifunctional NA structures.
