Archivio Istituzionale della RicercaThis work presents the ZnCr2- x FexO4 (x = 1, 1.25, 1.5, 1.75, 2) nanomaterials modified screen-printed carbon-based electrochemical sensors. The electrochemical sensor's performance was studied towards paracetamol sensing. The sensitivity and kinetic rate constant were evaluated for each sensor and compared. Found that the sensitivity and kinetic rate constant decreased as the amount of Cr decreased from x = 1 to 1.75. The best sensitivity and kinetic rate constant were observed for the pure ferrite sensor (x = 2).

Abstract
This work presents the ZnCr2- x FexO4 (x = 1, 1.25, 1.5, 1.75, 2) nanomaterials modified screen-printed carbon-based electrochemical sensors. The electrochemical sensor's performance was studied towards paracetamol sensing. The sensitivity and kinetic rate constant were evaluated for each sensor and compared. Found that the sensitivity and kinetic rate constant decreased as the amount of Cr decreased from x = 1 to 1.75. The best sensitivity and kinetic rate constant were observed for the pure ferrite sensor (x = 2).
