    摘要: This invention relates to a bone implant that includes a bioinert substrate covered with a ceramic layer containing a plurality of indentations. The total surface area of the indentations is 30-70% of the total surface area of the ceramic layer. This invention also relates to a method of preparing such a bone implant. The method includes: (1) affixing a ceramic layer on the surface of a bioinert substrate; (2) forming a plurality of indentations in the ceramic layer, wherein the total surface area of the indentations is 30-70% of the total surface area of the ceramic layer; and (3) immobilizing a biopolymer onto the ceramic layer via covalent bonding.
