Cortisol is a pivotal hormone regulating stress responses and linked to various health conditions, making precise continuous monitoring essential. Despite their non-invasive nature, conventional cortisol detection methods often suffer from inadequate sensitivity reliability at low concentrations, limiting diagnostic utility. To address these limitations, this study introduces novel paradigm for high using field-effect transistor (FET) sensors with dual-gate (DG) structures. The proposed sensor platform enhances through capacitive coupling without requiring external circuits. performance was evaluated by immobilizing monoclonal antibodies activated via 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide N-hydroxysuccinimide onto SnO2 thin film-based extended-gate. results revealed of 14.3 mV/dec in single-gate mode, which significantly increased 243.8 DG achieving limit 276 pM. Additionally, the stability were validated evaluating drift effects, confirming its ability provide accurate even artificial saliva environments containing interfering substances. In conclusion, DG-FET-based approach developed outperforms FET-based methods, enabling ultra-low concentrations. This holds significant potential diverse bioassays complex environments.
