Synthesis and Characterization of Polyaniline/ Graphene Nanocomposites and its Application as a Biosensor Detection of Glucose

Abstract This article discusses polyaniline and graphene (PANI/G) nanocomposites synthesized from aniline monomer and different weight percentages of graphene nanoparticles using chemical oxidation method at 0 °c. The characterization of the nanocomposites was conducted using X-ray diffraction (XRD) and scanning electron microscopy (SEM). SEM scans indicated that the PANI and its nanocomposite exhibited a spherical morphology, with particle diameters less than 35 nm, significantly impacted by graphene. The nanocomposite was investigated as a biological sensor, and the constructed sensor demonstrated its effectiveness in detecting glucose at various concentrations. The results indicate that nanocomposites possess significant promise for many biosensor applications.
