羟基磷灰石（HAP） Hydroxyapatite (HAP)

羟基磷灰石是人体和动物骨骼的主要无机成分，纳米羟基磷灰石被广泛应用于骨替代材料、整形美容、齿科、层析纯化和补钙剂中，特别在骨组织再生工程中具有骨诱导性。

Hydroxyapatite is the primary inorganic component of human and animal bones. Nano-hydroxyapatite is widely used in bone substitute materials, plastic and cosmetic surgery, dentistry, chromatographic purification, and calcium supplements, particularly in bone tissue regeneration due to its osteoinductive properties.
