A bioRxiv preprint describes a receptor-free electrochemical method for detecting cortisol using a defect-engineered graphene interface and a time-resolved measurement strategy. The researchers report low-nanomolar detection in artificial and biological interstitial fluids, supporting future work on continuous cortisol monitoring.
