A polyfluorene-molybdenum oxide nanocomposite (PF-MoO3) was successfully prepared in swollen liquidcrystalline (SLC) lamellar phase. The morphology, shape, and structure of the nanocomposite are characterized by fieldemission scanning electron microscopy (FESEM), X-ray powder diffraction (XRD), and Fourier transform infrared spectroscopy(FTIR). The obtained PF-MoO3 material was loaded over a glassy carbon electrode (GCE). The PF-MoO3/GCEwas employed as a working electrode for the detection of glucose by differential pulse voltammetry (DPV) and cyclicvoltammetry (CV) techniques. The determined limits of detection (LOD) and the limits of quantification (LOQ) fromCV were 7.90×105 M and 2.63×105 M, respectively. The calculated sensitivity of the PF-MoO3 electrode material forglucose was estimated to be 4.29×104A L mol1 cm2. The values of LOD and LOQ obtained from DPV data were7.05×105 M and 2.35×105 M, respectively. The results were in agreement with CV observations. Similarly, the glucosesensitivity for the PF-MoO3/GCE by DPV technique was 5.18×103A L mol1 cm2. In this research, we have developeda highly sensitive glucose sensor by modification of the GCE electrode surface with PF-MoO3 nanocomposite.
