This study explores the use of MXene-embedded porous carbon-based Cu₂O nanocomposite (Cu₂O/M/AC) as a sensing material for electrochemical glucose detection. The composite was synthesized using the coprecipitation method and characterized for its morphological and structural characteristics. The highly porous structure of activated carbon facilitated the incorporation of MXene and Cu₂O, enhancing charge transfer efficiency. Electrochemical techniques such as cyclic voltammetry, electrochemical impedance spectroscopy, and amperometric analysis confirmed the improved sensing parameters of the Cu₂O/M/AC composite. The composite exhibited two linear ranges for glucose detection with a limit of detection (LOD) of 1.96 μM. The linear ranges were 0.004 to 13.3 mM and 15.3 to 28.4 mM, with sensitivity values of 430.3 and 240.5 μA mM⁻¹ cm⁻², respectively. These findings suggest that the Cu₂O/M/AC nanocomposite is a promising material for non-enzymatic glucose sensors, offering high sensitivity, selectivity, and a wide linear range.This study explores the use of MXene-embedded porous carbon-based Cu₂O nanocomposite (Cu₂O/M/AC) as a sensing material for electrochemical glucose detection.
