In vitro degradation.

Notes: (A) SEM images of the samples before and after immersion in a Tris-HCl solution for 28 days. The arrows indicated that a porous structure had formed after the n-CS particles dissolved. (B) Concentration of Ca ions in the soaked solution. (C) Concentration of Si ions in the soaked solution.

Abbreviations: PEEK, polyetheretherketone; n-HA, nanohydroxyapatite; n-CS, nano-calcium silicate; SEM, scanning electron microscopy; Tris-HCl, trihydroxymethyl aminomethane-hydrochloric acid.
