Phosphorylated dendronized poly(amido amine)s as protein analogues for directing hydroxylapatite biomineralization

摘要

Dendronized poly(amido amine)s (DPs) bearing tri-phosphate or bis-phosphonate peripheral groups are synthesized. These worm-tike DPs can template the formation of BMSCs adhesive hydroxylapatite (HA) on the nano-scale, or self-assemble into mineral-collecting microfibers on the micro-scale, exhibiting similar functions of non-collagenous proteins (NCPs) in the natural biomineralization process of HA.
