该载体是由软体动物的硬组织改性而成的羟基磷灰石材料,其微观结构是由5nm～500nm大小(即纳米级尺寸)的羟基磷灰石片状体、棒状体或丝状体自组织而成的0.1μm～μm的中空微球。该羟基磷灰
The carrier is a hydroxyapatite modified by the hard tissue of mollusks. The microstructure of the hydroxyapatite material is composed of a hydroxyapatite platelet with a size of 5 nm to 500 nm (ie nanometer size), a rod-like body or a filament Self-organized 0.1μm ~ μm hollow microspheres. The hydroxyapatite
