Herein, the strontium bioactive glass with ferrite composites is studied for the application of biocompatibility and magnetic hyperthermia. The bioactive glass SrBG (46.1SiO2–21.9CaO–24.4Na2O–2.6P2O5–5SrO) prepared by the melt quench technique at 1400 °C and manganese ferrite (MnFe2O4) prepared by the modified microwave reflux oven are mixed together and sintered at 400 °C for 6 h for making composites. The in vitro bioactivity of these composites is observed by immersing in simulated body fluid (SBF). The growth of the precipitated hydroxyapatite phase observed after SBF treatment is confirmed by the X‐ray diffractometer (XRD), Fourier transform infrared (FTIR) spectrometer, and scanning electron microscope (SEM) results. The in vitro cell viability assessment of these composites with MG‐63 cell lines indicates that the composites are biocompatible in nature. Furthermore, these composites show the antibacterial effect on the E. coli and S. Aureus bacteria cells. The room temperature superparamagnetic behavior accompanied by the heating ability in these composites proves their potential role for hyperthermia applications.

超顺磁性锰铁氧体和锶生物玻璃纳米复合材料：热疗应用的增强的生物相容性和抗菌性能。
在本文中，研究了具有铁氧体复合材料的锶生物活性玻璃在生物相容性和磁热疗中的应用。在1400°C下通过熔融淬火技术制备的生物活性玻璃SrBG（46.1SiO 2 –21.9CaO–24.4Na 2 O–2.6P 2 O 5 –5SrO）和锰铁氧体（MnFe 2 O 4将由改进的微波回流烤箱制备的）混合在一起，并在400°C下烧结6小时以制备复合材料。通过浸入模拟体液（SBF）中观察到这些复合材料的体外生物活性。X射线衍射仪（XRD），傅立叶变换红外（FTIR）光谱仪和扫描电子显微镜（SEM）证实了SBF处理后观察到的沉淀羟基磷灰石相的生长。这些复合物与MG-63细胞系的体外细胞生存力评估表明，该复合物具有自然生物相容性。此外，这些复合材料对大肠杆菌和金黄色葡萄球菌细菌细胞具有抗菌作用。这些复合材料的室温超顺磁性行为以及加热能力证明了它们在高温应用中的潜在作用。
