Microstructure of the BCP scaffold, nHA powder, and the nHA-coated BCP scaffold. (A) FESEM image of a polished surface of a BCP scaffold. (B) TEM micrograph of nHA powder. (C) Low magnification FESEM image displaying the formation of a nHA crystal deposition layer on the BCP scaffold surface. Similar nHA crystals were also observed on the walls of pores within the BCP scaffold. (D) High magnification image of the deposited nano-crystal layer.
