Abstract
Bone defects caused by trauma, tumor, congenital abnormality and osteoarthritis, etc. have been substantially impacted the lives and health of human. Artificial bone implants, like bioceramic-based scaffolds, provide significant benefits over biological counterparts and are critical for bone repair and regeneration. However, it is highly probable that bacterial infections occur in the surgical procedures or on bioceramic-based scaffolds. Therefore, it is of great significance to obtain bioceramic-based scaffolds with integrative antibacterial and osteogenic functions for treating bone implant-associated infection and promoting bone repair. To fight against infection problems, bioceramic-based scaffolds with various antibacterial strategies are developed for bone repair and regeneration and also have made great progresses. This review summarizes recent progresses in bioceramic-based scaffolds with antibacterial function, which include drug-induced, ion-mediated, physical-activated and their combined antibacterial strategies according to specific antibacterial mechanism. Finally, the challenges and opportunities of antibacterial bioceramic-based scaffolds are discussed. Bioceramic-based scaffolds with antibacterial function (BSAF) are reviewed. BSAF have a great potential in treating bone infection and promoting bone repair. Antibacterial strategies of BSAF include drug, ion, physical and combined ways. The combined strategy may be the optimal approach in fighting bone infection. Limitations, challenges and perspectives of BSAF are discussed.

In vitro study of a novel multi-substituted hydroxyapatite nanopowder synthesized by an ultra-fast, efficient and green microwave-assisted method. MATERIALS SCIENCE & ENGINEERING. C, MATERIALS FOR BIOLOGICAL APPLICATIONS 2020; 117:111310. [PMID: 32919671 DOI: 10.1016/j.msec.2020.111310] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/02/2020] [Revised: 07/09/2020] [Accepted: 07/17/2020] [Indexed: 12/13/2022]
Abstract
In order to improve the biological activity of hydroxyapatite (HA), a multi-substituted HA (SHA) nanopowder with the chemical composition of Ca9.5Mg0.25Sr0.25(PO4)5.5(SiO4)0.5(OH)1.2F0.8 was synthesized using the microwave-assisted method. X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and transmission electron microscopy (TEM) revealed that all ions were substituted in the HA crystal lattice. The HA and SHA nanoparticles had a semi-spherical morphology with the average size of 90 and 80 nm, respectively. In-vitro bioactivity assessments showed that after the 28-day immersion of the samples in the simulated body fluid, the morphology of the precipitated apatites on the surface of the HA sample still consisted of spherical particles with a cauliflower-like structure. However, in the SHA sample, the morphology of the precipitated apatites was changed to a nanorod-like one similar to the bone-like apatite, which may be attributed the presence of Sr in the precipitated apatites. The results showed that the release of the substituted ions not only had no adverse effect on the cell viability and cell attachment, but also enhanced the alkaline phosphatase activity of MG63 osteoblast like cells in the SHA group, as compared to the HA and control groups. The results indicated that the simultaneous substitution of Si, Mg, Sr, and F in HA nanoparticles could effectively promote bioactivity, cell proliferation and differentiation. This novel HA composition could be, therefore, well used for implant coating, bone tissue engineering and other orthopedic applications.
