Facet-Specific Mineralization Behavior of Nano-CaP on Anatase Polyhedral Microcrystals
Biomimetic mineralization
of nanocalcium phosphate (CaP) on metal
oxide surfaces has gained great interest because of their relevance
to osseointegration performance of implant materials. However, precisely
controlling the nucleation behavior of mineralized nano-CaP on metal
oxide at selective sites still remains a challenge. Here, we demonstrate
a phenomenon on facet-specific mineralization on anatase TiO<sub>2</sub> polyhedral microcrystals organized by two facets of {101} and {001}
in complete cell culture medium: nano-CaP covers up {101} facets,
while there are a few on {001} facets. The comparative experimental
results indicate that the preadsorbed fetal bovine serum (FBS) protein
on {001} facets might play a barrier role in preventing sequential
nucleation of nano-CaP. This work thus provides insight into the understanding
of mineralization on metal oxides, and a way to control the mineralization
