Abstract
AbstractMineralization of hydroxyapatite mineralized by acidic metal oxides has attracted substantial research interest in the research and development of orthopedic substitutes. In this study, Polycaprolactone (PCL) nanofibers with nano‐tantalum oxide (Ta2O5) were successfully fabricated through electrospinning. The scaffold simulates the mineralization process of hydroxyapatite in simulated body fluid. However, in the process of mineralization, there is a chemical reaction between hydrophobic scaffolds and acid oxides, which is believed to have a significant impact on the biological effects of the scaffolds. The results of SEM, EDS, XRD, Mapping, FTIR, GPC, 13CNMR, and 1HNMR explain the principle of hydroxyapatite mineralization by Ta2O5 and the reason why the composite scaffold is blurred, that is, the carbonyl carbon of PCL attacked by the surface hydroxyl groups of Ta2O5 to catalyze its ring‐opening polymerization to synthesize PCL/Ta2O5 nanocomposites in one step. In order to accurately explore the effect of this reaction on the metabolism of biological macromolecules in the future, we provide a detailed route of Ag Nanoparticles ‐Dimercaptosuccinic acid@Transcription activator (AgNPs‐DMSA@TAT) probe synthesis. The results provide a reference for the sedimentation of hydroxyapatite induced by acid oxides and its effect on traditional electrospun fiber scaffolds.
