| Sample | Particle | Extraction Solution | |||
|---|---|---|---|---|---|
| Ca + Co/P | Xco (%) | Ca (ppM) | Co (ppM) | P (ppM) | |
| PBS | N.D. | N.D. | N.D. | N.D. | 541 |
| DC-CoHA | 1.72 | 14.0 | 1.04 | 1.45 | 434 |
| PC1-CoHA | 1.67 | 14.0 | 1.68 | 1.86 | 429 |
| PC2-CoHA | 1.68 | 13.0 | 1.21 | 1.72 | 425 |
The extraction solution was obtained by immersed the powder in phosphate-buffered saline (PBS) at 37 °C for 7 days.
