Abstract

Laser-induced graphene (LIG) has received great interest as a potential candidate for electronic and sensing applications. In the present study, we report the enhanced performance of a manganese carbonate-decorated LIG (MnCO₃/LIG) composite electrode material employed for electrochemical glucose detection. Initially, the porous LIG was fabricated by directly lasing poly(ether sulfone) membrane substrate. Then, the MnCO₃/LIG composite was synthesized via a hydrothermal method. Later, MnCO₃/LIG was immobilized onto a glassy carbon electrode surface and employed for glucose detection. The structure of the MnCO₃/LIG composite was carefully characterized. The influence of the MnCO₃/LIG composite on the performance of the electrode was investigated using cyclic voltammetry curves. The MnCO₃/LIG composite exhibited an excellent sensitivity of 2731.2 μA mM^-1 cm^-2, and a limit of detection of 2.2 μM was obtained for the detection of glucose. Overall, the performance of the MnCO₃/LIG composite was found to be superior to that of most of the MnCO₃-based composites.
