We are very happy to see Dr Şahin has published a paper in the inaugural issue of Nature Sensors journal. This paper covers the work he has conducted during his Fulbright Fellowship at Northwestern University, Querry Simpson Institute for Bioelectronics.
This report presents a few concepts for wearable sweat diagnostic technologies, centered on two key innovations. First, it describes paper-based lateral flow assays (LFAs) that perform colorimetric detection of biochemical markers in sweat, using microliter volumes collected through soft, skin-mounted microfluidic networks. Second, it introduces systems of materials-based valves, electronically actuated triggers, and self-powered electrochromic displays that enable time-resolved monitoring of sweat chemistry by integrating with these LFA-embedded microfluidic platforms.
While these approaches are broadly relevant across different biomarkers, the paper highlights their application to measuring cortisol in sweat and demonstrates relationships between sweat cortisol levels and those in saliva and blood.
