Quantification of ALP activity on the substrates after osteogenic induction for 7, 10, and 14 days.

Notes: ALP activity was normalized to the corresponding total protein content. *Significant difference compared with HA/P66 (P<0.05). #Significant difference compared with PDA-HA/P66 (P<0.05).

Abbreviations: HA/P66, hydroxyapatite/polyamide 66; PDA, polydopamine; PDA-HA/P66, polydopamine coating on hydroxyapatite/polyamide 66; HA-PDA-HA/ P66, hydroxyapatite coating formation on hydroxyapatite/polyamide 66 assisted by polydopamine.
