“…Because the HAp nanorods can mimic natural bone structure, they are more suitable for use in bone regeneration. 11 The hydrothermal method is a simple method that can be used for HAp nanorod synthesis. The hydrothermal process induces nanocrystalline growth that strongly depends on the dissolution rate of raw materials.…”

“…Up to present, abundant HAp nanomaterials with distinct morphologies have been synthesized, such as nanosheets [6] , nanoparticles [7], nanorods [8] and nano needles [9] , and their adsorption performances have been also investigated. Among them all, HAp nanorods have became more popular due to their outstanding physicochemical properties and other superior properties [10][11][12] . Unfortunately, most of the synthetic methods for HAp nanorods are complex, cumbersome, expensive and not environmentally friendly for the moment [10][11][12] .…”

Pure hydroxyapatite (HAp) nanorods have been synthesized successfully by coprecipitation method with only three requisite cheap reactants. The product was characterized by XRD, FTIR and SEM. The adsorption performances of HAp nanorods were performed by measuring the removal of Direct Red 28 (DR 28) in water solution with a serials of adsorption tests, and the adsorption isotherms were also studied. The results showed that the solution pH, contact time and initial concentration of dye solution played critical roles in adsorption of DR 28 onto HAp nanorods. Furthermore, the maximum adsorption capacity was calculated to be 166.94 mg/g, suggesting that the HAp nanorods demonstrated strong ability to remove DR 28 from aqueous solution.

Introduction An antibacterial and pro-osteogenic coaxially electrospun nanofiber guided bone regeneration (GBR) membrane was fabricated to satisfy the complicated and phased requirements of GBR process. Methods In this study, we synthesize dual-functional coaxially electrospun nanofiber GBR membranes by encapsulating parathyroid hormone (PTH) in the core layer and magnesium oxide nanoparticles (MgONPs) in the shell layer (MgONPs-PCL/PTH-PCL). Herein, the physicochemical characterization of MgONPs-PCL/PTH-PCL, the release rates of MgONPs and PTH, and antibacterial efficiency of the new membrane were evaluated. Furthermore, the pro-osteogenicity of the membranes was assessed both in-vitro and in-vivo. Results We successfully fabricated a coaxially electrospun nanofiber MgONPs-PCL/PTH-PCL membrane with the majority of nanofibers (>65%) ranged from 0.40~0.60μm in diameter. MgONPs-PCL/PTH-PCL showed outstanding antibacterial potential against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) through the release of MgONPs. We also discovered that the incorporation of MgONPs significantly prolonged the release of PTH. Furthermore, both the in-vivo and in-vitro studies demonstrated that high dosage of PTH promoted pro-osteogenicity of the membrane to improve bone regeneration efficacy with the presence of MgONPs. Conclusion The new composite membrane is a promising approach to enhance bone regeneration in periodontitis or peri-implantitis patients with large-volume bone defects.
