In Situ Synthesis of a Hydroxyapatite and Reduced Graphene Oxide Composite for Potential Electrochemical Biosensing Applications.

ABSTRACT: Hydroxyapatite/reduced graphene oxide (HA/rGO) composites are extensively used in numerous applications, including tissue engineering, energy storage, catalysis, and electrochemical sensing. In this study, a novel microwave hydrothermal-assisted coprecipitation method was implemented to synthesize an in situ HA/rGO composite for potential electrochemical biosensing applications. The structural, optical, and morphological properties were thoroughly analyzed using XRD, Raman spectroscopy, FTIR, STXM, and SEM. Rietveld refinement confirmed the presence of a hexagonal crystalline phase in the HA/rGO composite with a mean crystallite size of 28.1 nm. Raman spectroscopy revealed characteristic vibrational modes of each precursor, while STXM spectra displayed electronic transitions corresponding
