A new biocomposite including Poly (methyl methacrylate)/Ce-Cu substituted apatite/Egg white (Ovalbumin) (PMMA/MHAP/EW) has been effectively manufactured via lyophilization technique. The reason to plan such biocomposite is to investigate for a perfect simple which may bio-imitate the constitution of natural bone for hard tissue designing regarding appropriate biodegradability, biocompatibility, and bactericidal properties. The FTIR and XRD spectra of prepared biocomposite showed the considerable intermolecular interface between the different constituents of the biocomposites. The examination of SEM pictures of the biocomposites demonstrated that the addition of EW affected the exterior morphology while a superior in-vitro biocompatibility has been seen in PMMA/MHAP/EW than in PMMA/MHAP in view of ALP, hemocompatibility and mineralized extracellular matrix studies, referring a more superior probability for assembly straight attach to living hard tissues if embedded. Additionally, cytocompatibility assay exposed the superior non-lethal character of prepared biocomposites to MG-63 cells when contrasted with PMMA/MHAP. The relative biodegradation studies of prepared biocomposites exposed a superior degradation rate for Comp-3. Besides, PMMA/MHAP/EW showed enhanced antibacterial property against both E. coli as well as S. aureus microbes with respect to PMMA/MHAP. These findings have set PMMA/MHAP/EW biocomposites on the platform to be utilized as a prospective option biomaterial for hard tissue designing.
一种新型的生物复合材料,包括聚甲基丙烯酸甲酯/铈-铜取代磷灰石/蛋清(卵白蛋白)(PMMA/MHAP/EW),已通过冷冻干燥技术有效地制造出来。设计这种生物复合材料的原因是为了寻找一种理想的简单物质,它可以通过适当的生物降解性、生物相容性和杀菌性能来模拟天然骨的结构,用于硬组织设计。制备的生物复合材料的 FTIR 和 XRD 光谱表明,生物复合材料的不同成分之间存在相当大的分子间界面。生物复合材料的 SEM 图片的检查表明,EW 的添加影响了外部形态,而 PMMA/MHAP/EW 的体外生物相容性优于 PMMA/MHAP,这是从 ALP、血液相容性和矿化细胞外基质研究的角度来看的,如果嵌入的话,更有可能直接组装到活的硬组织上。此外,细胞相容性试验表明,与 PMMA/MHAP 相比,制备的生物复合材料对 MG-63 细胞具有更好的非致命特性。制备的生物复合材料的相对降解研究表明,Comp-3 的降解速率更高。此外,PMMA/MHAP/EW 对大肠杆菌和金黄色葡萄球菌的抗菌性能均优于 PMMA/MHAP。这些发现使 PMMA/MHAP/EW 生物复合材料成为硬组织设计中具有应用前景的生物材料的选择。
