Abstract
This study presents a real-time impedimetric biosensor to detect cortisol in human serum in small volumes in the range of 1-20 µL. Continuous monitoring of cortisol is closely related to maintaining healthy physiological conditions. A 28-well plate biosensor chip was built after several steps of fabrication. The achieved nanowell array structure provides enhanced electrochemical sensitivity which enables to detect cortisol at high salt concentration of human serum. Human serum samples were collected to compare the sensor response with results from the ELISA method. The robust performance of the device was validated from the proportional response of both measurements.
