Paper Title:
Apatite-Coated Poly(lactic acid) Composites with Cell-Compatibility Prepared by a Biomimetic Method
  Abstract

A new type of poly(lactic acid) (PLA)/calcium carbonates hybrid membrane incorporated with silicon, which is suggested to stimulate the formation of bones, was prepared using aminopropyltriethoxysilane (APTES) for bone repair materials. Carboxyl groups in PLA made a chemical bond with amino groups in APTES, resulting in the formation of the hybrid membrane. The membrane formed hydroxycarbonate apatite (HCA) on its surface after 3 days of soaking in simulated body fluid (SBF). X-ray energy dispersive spectroscopy showed the HCA layer includes Si with Ca and P. A result of osteoblast-like cellular proliferation on the substrates that the membrane coated with silicon-containing HCA had much higher cell-proliferation ability than the membrane.
