Sensitive electrochemical detection of total sugars in food using NiFe alloy nanowires.

ABSTRACT: An innovative electrochemical sensor is introduced based on a nickel-iron (NiFe) alloy, designed for rapid, cost-effective, and straightforward sugar determination in food. The sensor features vertically aligned NiFe nanowire arrays, providing a high surface area for enhanced performance. Sensor calibration was performed for various mono- and disaccharide reducing sugars. In the linear range 0.05-0.3 mM, sensors exhibited a sensitivity of 0.642 µA µM⁻¹·cm⁻², with a detection limit of 2.57 µM for monosaccharides and a limit of quantification of 14 µM. In the same linear range, for disaccharides a sensitivity of 0.355 µA µM⁻¹·cm⁻², a detection limit of 4.62 µM and a limit of quantification of 14 µM were found. The sensors displayed excellent selectivity towards reducing sugars with negligibl
