The repair of bone defects caused by osteosarcoma is still a significant clinical issue, and new scaffolds need to be developed to solve this problem. The ocean is a treasure trove for developing new biomedical materials, and coral is widely thought to be suitable as a scaffold for bone implant materials due to its porous structure and mechanical properties. Selenium is known for its antioxidant and antitumor effects, inducing tumor cell cycle arrest. In this study, we hydrothermally transformed corals to grow a hydroxyapatite layer on the scaffold surface (CHAp) and combined it with selenium to obtain selenium-doped scaffolds (Se-CHAp) without affecting the porous structure of the coral. The research successfully validates their biocompatibility and the antitumor efficacy against 143B osteosarcoma cells. The results indicate that the Se-CHAp scaffolds yielded an obvious inhibitory effect on the proliferation of osteosarcoma cells, highlighting that they have huge prospects for application in biomedical technology.
