Mean values of ion release from CNTT–HA (A) and CNTT–BGN (B), measured by ICP-mass spectrometry (mean values). The concentration of released Zn, Ca, and Si ions from immersed CNTT–HA and CNTT–BGN structures in phosphate buffer saline represents the degradation rate of the bioactive ceramics. The concentration of Zn ions was measured to quantify the amount of residual ZnO from the fabrication process. (Each experiment was carried out using three samples. Error bars: standard deviation.)
