文摘

Carbonated hydroxyapatite is a main inorganic component of hard tissues in vertebrates, which usually appears as orderly arranged superstructures in tissues and exhibits excellent biological and mechanical properties. Recently, mimicking the structure and composition of organisms in the field of biomaterials and tissue engineering has caused much attention. Herein, a family of orderly arranged textures composed of two-dimensional carbonated hydroxyapatite in nanoscale was prepared in the complex matrix of succinylated gelatin and cetyltrimethyl ammonium bromide, which is an analogue of bone in calcified turkey tendon. The building blocks of carbonated hydroxyapatite nanosheets elongate along the c-axis direction and self-organize into well-aligned bundles. This study may offer an example to design and synthesize laminated materials and may provide new evidence in support of the hypothesis that hierarchical structures in nature result from cooperative interactions between biological membrane and crystal growth.
