The aim of this study is to prepare rhBMP-2/ACP nanocarriers and study their biocompatibility. First, ACP nanocarriers were obtained by chemical synthesis, and rhBMP-2 was loaded onto ACP nanocarriers by electrostatic attraction to form nanocarriers. Subsequently, biocompatibility experiments were conducted. The toxicity of the nanocarriers to osteoblasts was detected by MTT assay in vitro, and the biological distribution and toxicity of the nanocarriers to surrounding tissues were observed by fluorescence localization experiment in vivo. Finally, the preparation and biocompatibility of rhBMP-2/ACP nanocarriers were analyzed according to the experimental results.Keywords: rhBMP-2/ACP nanocarriers, preparation, biocompatibility
