Mn/nHA涂层CF/PEEK复合材料的制备及体外成骨活性评价
Preparation and in vitro Osteogenic Activity Evaluation of Mn/nHA Coated CF/PEEK Composite
摘要
Abstract
Carbon fiber/polyetheretherketone(CF/PEEK)has been widely used in the field of bone repair.However,its bio-inert nature results in poor osseointegration,which significantly limits its long-term stability and bone repair efficacy in clinical applications.Here,a manganese-doped nano-hydroxyapatite(Mn/nHA)coating was constructed on the surface of CF/PEEK using a liquid-phase self-assembly strategy of inorganic nanoparticles.The experimental results demonstrated that both Mn/nHA and nHA coatings significantly improved the surface roughness and hydrophilicity of CF/PEEK.Further in vitro studies revealed that after co-culturing with rat mesenchymal stem cells(BMSCs)for 7 d,the relative cell viability of the Mn/nHA-and nHA-coated materials reached as high as 180%and 159%,respectively,indicating a pronounced pro-proliferative effect.Additionally,alizarin red staining and reverse transcription-polymerase chain reaction(RT-PCR)analysis showed that both coatings enhanced cell mineralization and osteogenic differentiation on the material surface,with the Mn/nHA coating exhibiting a stronger promoting effect.关键词
