Synthesis of Titanium Oxide Modified Al-Zn-Doped Hydroxyapatite Composites and Their Antibacterial Activity
This work focuses on the synthesis of aluminum and zinc-doped titanium oxide-modified hydroxyapatite composites by the sol–gel process. Al-Zn@TiO2/Ca10-XAlXZnX(PO4)6(OH)2 (XAl/Zn = 0.5%) (Al-Zn:TiO2-HAp) composites were synthesised and annealed at two different temperatures (500°C to 600°C). The structural, morphology and composition of the Al-Zn:TiO2-HAp samples was investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX) techniques respectively. Furthermore, UV–vis spectral analysis was used to investigate the optical characteristics of the samples. The potential antibacterial efficacy of the produced Al-Zn:TiO2-HAp composite samples was tested against bacterial pathogens Shigella flexneri (S. flexneri) and Pseudomonas aeruginosa (P. aeruginosa), respectively. The antimicrobial investigation showed that Al-Zn:TiO2-HAp composites effectively suppress the development of S. flexneri and P. aeruginosa. Furthermore, raising the annealing temperature of the Al-Zn:TiO2-HAp composites can significantly increase their ability to prevent bacterial growth.
