摘要

本研究首次研究了掺杂比例对500℃烧结b掺杂羟基磷灰石（HA）结构和生物学性能的影响。为此，合成了1、2、4和8 mol% b掺杂的HA基团。用傅里叶变换红外光谱（FTIR）验证了PO43 -和BO33 -基团的存在。x射线衍射（XRD）分析表明，B比的增加导致HA相百分比、结晶度和晶粒尺寸呈下降趋势。Ca/(P + B)比值也随掺杂比的增加而减小。B被纳入HA结构，产率约为50%。此外，b掺杂显著降低了各组的平均粒径。BET分析结果显示，随着B比的增加，基团的表面积也随之增加。总的来说，用4 mol% B掺杂透明质酸被证明对人脂肪来源干细胞（hADSCs）具有增殖和成骨作用。我们的研究结果表明，在500°C下烧结的b掺杂HA有望用于骨组织工程应用。

Synthesis and characterization boron-doped hydroxyapatite for bone tissue engineering applications

In this study, the effect of dopant ratio on structural and biological properties of B-doped hydroxyapatite (HA) sintered at 500 °C was investigated for the first time. For this purpose, 1, 2, 4 and 8 mol% B-doped HA groups were synthesized. Presence of PO₄³⁻ and BO₃³⁻ groups were verified with Fourier-transform infrared spectroscopy (FTIR). X-ray diffraction (XRD) analysis revealed that increasing the B ratio led to a decreasing trend for HA phase percentage, crystallinity, and crystallite size. Similarly, Ca/(P + B) ratio decreased with increasing dopant ratio. B was incorporated into the HA structure with around 50 % yield. Moreover, mean particle size significantly decreased by B-doping for all groups. Concordantly, BET analysis revealed that the surface area of the groups increased with increasing B ratio. Overall, doping of HA with 4 mol% B was shown to provide both proliferative and osteogenic effects on human adipose derived stem cells (hADSCs). Our findings suggest that B-doped HA sintered at 500 °C holds promise for bone tissue engineering applications.
