| Abstract Scope |
Hydroxyapatite (HA) is widely employed for the repair or replacement of damaged hard tissue due to its compositional and structural similarities to natural HA. HA’s hexagonal crystal structure allows for modification with various ion substitution(s). Thus, metal ions such as Ag+ and Cu2+ have gained attention due to their antibacterial capabilities with their successful incorporation being proven by several studies. Limited research has been conducted on the quantity of ions incorporated and how their quantity influences the crystal structure and subsequent properties. A series of Ag-HA and Cu-HA powders with varying ion substitution (mol%) are synthesized and evaluated by X-ray characterization to observe the effects of ion content on the lattice parameters and site occupancies. Ion leaching in aqueous solution is evaluated using inductively coupled plasma optical emission spectroscopy (ICP-OES) and the agar diffusion method is used to establish antibacterial efficacy. |
