Radiopaque mesoporous glasses were successfully synthesized.

The addition of ZrO₂ into the network did not affect the bioactivity, resulting in a highly bioactive mesoporous glass.

Radio-opaque mesoporous glass particles have the potential to be used as dispersed phase in composite injectable bone cements.

The ZrO₂-containing mesoporous glasses are useful for the postoperative X-ray investigation of patient壮s bone.
