Glucose is one of the most important monosaccharides found in food, as a part more complex structures, which primary energy source for brain and body. Thus, monitoring glucose concentration food biological samples order to maintain healthy lifestyle. Herein, an electrochemical biosensor was fabricated by immobilization oxidase (GOX) onto poly(3,4-ethylenedioxythiophene):4-sulfocalix [4]arene (PEDOT:SCX)/MXene modified electrode. For this purpose, firstly, PEDOT synthesized presence SCX (counterion) chemical oxidative method. Secondly, MXene (a 2D layered material) using high-temperature furnace under nitrogen atmosphere. After that, PEDOT:SCX/MXene (1:1) dispersion prepared ultrasonication later utilized prepare hybrid film. A successful formation film confirmed HR-SEM, Fourier transform infrared (FT-IR), Raman spectroscopies. Due biocompatibility nature, GOX carried out chitosan PEDOT:SCX/MXene/GCE. Moreover, properties PEDOT:SCX/MXene/GOX/GCE studied through cyclic voltammetry amperometry methods. Interestingly, stable redox peak FAD-GOX observed at formal potential -0.435 V on indicated direct electron transfer between enzyme electrode surface. also exhibited linear response against concentrations range from 0.5 8 mM. The effect pH, sensors reproducibility, repeatability sensor were studied. Finally, new successfully applied detect commercial fruit juice sample with satisfactory recovery.
