Abstract
BACKGROUND: This study aimed to analyze the bioactivity and biocompatibility of silicon carbide (SiC) foam coated with one of two kinds of zeolite. METHODS: The surface charges, protein adsorption ability and mineralization ability were compared between silicalite-1/SiC foam and ZSM-5/SiC foam. RESULTS: Proliferation and differentiation of primary osteoblasts seeded on two types of materials were significantly higher when compared with uncoated SiC foam after 7 d. There was no significant difference in the bioactivity between silicalite-1/SiC foam and ZSM-5/SiC foam. Silicalite-1/SiC foam and ZSM-5/SiC foam had no cytotoxic effect on primary osteoblasts. CONCLUSIONS: These results suggest both silicalite-1/SiC foam and ZSM-5/SiC foam have the potential for use as novel bone replacement materials.
