Poly(ε-Caprolactone)-Based Composites Modified With Polymer-Grafted Magnetic Nanoparticles and L-Ascorbic Acid for Bone Tissue Engineering
The aim of this study was to develop multifunctional magnetic poly(ε-caprolactone) (PCL) mats with antibacterial properties for bone tissue engineering and osteosarcoma prevention. To provide good dispersion of magnetic iron oxide nanoparticles (IONs), they were first grafted with PCL using a novel three-step approach. Then, a series of PCL-based mats containing a fixed amount of ION@PCL particles and an increasing content of ascorbic acid (AA) was prepared by electrospinning. AA is known for increasing osteoblast activity and suppressing osteosarcoma cells. Composites were characterized in terms of morphology, mechanical properties, hydrolytic stability, antibacterial performance, and biocompatibility. AA affected both the fiber diameter and the mechanical properties of the nanocomposites. All produced mats were nontoxic to rat bone marrow-derived mesenchymal cells; however, a composite with 5 wt.% of AA suppressed the initial proliferation of SAOS-2 osteoblast-like cells. Moreover, AA improved antibacterial properties against Staphylococcus aureus and Escherichia coli compared to PCL. Overall, these magnetic composites, reported for the very first time, can be used as scaffolds for both tissue regeneration and osteosarcoma prevention.
期刊介绍:
Journal of Biomedical Materials Research – Part B: Applied Biomaterials is a highly interdisciplinary peer-reviewed journal serving the needs of biomaterials professionals who design, develop, produce and apply biomaterials and medical devices. It has the common focus of biomaterials applied to the human body and covers all disciplines where medical devices are used. Papers are published on biomaterials related to medical device development and manufacture, degradation in the body, nano- and biomimetic- biomaterials interactions, mechanics of biomaterials, implant retrieval and analysis, tissue-biomaterial surface interactions, wound healing, infection, drug delivery, standards and regulation of devices, animal and pre-clinical studies of biomaterials and medical devices, and tissue-biopolymer-material combination products. Manuscripts are published in one of six formats:
• original research reports
• short research and development reports
• scientific reviews
• current concepts articles
• special reports
• editorials
Journal of Biomedical Materials Research – Part B: Applied Biomaterials is an official journal of the Society for Biomaterials, Japanese Society for Biomaterials, the Australasian Society for Biomaterials, and the Korean Society for Biomaterials. Manuscripts from all countries are invited but must be in English. Authors are not required to be members of the affiliated Societies, but members of these societies are encouraged to submit their work to the journal for consideration.
