Abstract

Abstract In this work, sintered pellets of a silica-based bioactive glass were dip-coated with a biocompatible natural-derived polymer in order to investigate the influence of the organic coating on the glass bioactivity. After the sintering process optimization, uncoated and coated pellets have been characterized by means of scanning electron microscopy with energy dispersive spectroscopy (SEM, EDS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and pH measurements, after the immersion in a simulated body fluid (SBF). An increased apatite forming ability and a better control of the pH during soaking of the samples in SBF were observed in the presence of the biopolymer. This result opens a new insight on the simple fabrication of highly bioactive hybrid inorganic-organic materials for medical applications.

生物聚合物涂层生物活性玻璃上磷灰石的增强沉淀

摘要本研究采用生物相容性天然聚合物浸渍法制备硅基生物活性玻璃颗粒，研究有机涂层对玻璃生物活性的影响。烧结工艺优化后，在模拟体液(SBF)中浸泡后，通过扫描电镜、能谱分析(SEM, EDS)、x射线衍射(XRD)、傅里叶变换红外光谱(FT-IR)和pH测量对未包覆和包覆微球进行了表征。在生物聚合物存在的情况下，样品在SBF中浸泡时磷灰石形成能力增强，pH控制更好。这一结果为简单制造用于医疗应用的高生物活性无机-有机杂化材料提供了新的见解。
