Abstract

Controlling the immune response and enhancing osteogenesis are essential for the long-term success of biomaterial implantation. Although polyetheretherketone (PEEK) is widely used in orthopedic implants, its inherent bioinertness and poor osteogenic capacity limit its use in clinical applications. In this study, curcumin (CCM) and zeolitic imidazolate frameworks-8 nanoparticles (ZIF-8 NPs) were introduced onto PEEK substrate to obtain the SPEEK-CCM@ZIF-8 (SPZC) system, which enhances osseointegration through early immunomodulation. SPEEK-CCM@ZIF-8 induces macrophage polarization towards M2 phenotype to reduce inflammation, promotes osteogenic differentiation capacity of bone marrow mesenchymal stem cells (BMSCs), and enhances the osseointegration and osteogenic capacity of PEEK implants. In vivo evaluation further confirmed the enhanced osteointegration effect of SPZC. Our results suggest that the CCM@ZIF-8 coating confers good osteogenic capacity to PEEK and that SPZC will have great potential as an implant.

期刊介绍： Composites Science and Technology publishes refereed original articles on the fundamental and applied science of engineering composites. The focus of this journal is on polymeric matrix composites with reinforcements/fillers ranging from nano- to macro-scale. CSTE encourages manuscripts reporting unique, innovative contributions to the physics, chemistry, materials science and applied mechanics aspects of advanced composites. Besides traditional fiber reinforced composites, novel composites with significant potential for engineering applications are encouraged.
