Novel pectin from Parkia biglobosa pulp mediated green route synthesis of hydroxyapatite nanoparticles


Hydroxyapatite (HAP) nanoparticles were synthesized using pectin from pulp of P. biglobosa as green template. This was achieved at different concentrations (0.1, 0.5 and 1%) of pectin. The HAP nanoparticles mediated by pectin were characterized using Fourier Transform infrared (FTIR), Scanning electron Microscopy (SEM) and Xray Diffraction (XRD). Structure and morphology of the synthesized HAP indicate that discrete and less agglomerated particles were produced at low concentration (0.1%) of pectin. The HAP nanoparticles produced, with crystallite size ranging from 17.5 to 26.3 nm, inhibited the growth of selected bacteria used for the study. Findings from this study suggest that P. biglobosa pulp pectin can serve as a green template for the production of HAPnanoparticleswhichareconsideredtobepromisingandversatilebioactivematerialsinenzymetechnology, biomedical and tissue engineering.
