Abstract
Constant high cortisol levels resulting from chronic stress impair mental health and performance, yet real-time monitoring remains challenging. For non-invasive analysis, an electrochemical cortisol sensor was developed using carbon nanotubes (CNTs) non-covalently functionalized with pyrene derivatives (PY). Functionalized CNTs enabled cortisol interaction, with sensitivity and dynamic range evaluated through differential pulse voltammetry (DPV). Molecular dynamics (MD) simulations further clarified cor-tisol–pyrene interactions. This approach lays the groundwork for simple, non-invasive stress monitoring.
