为了提高玉米蛋白的骨诱导性和骨结合性,以促进其在骨组织工程领域中的应用,将玉米蛋白多孔支架材料浸泡于5倍模拟体液(5×SBF)中,尝试在不同的条件下对玉米蛋白多孔支架材料表面进行仿生矿化。通过场发射扫描电镜( SEM)观察仿生矿化后多孔支架材料各个表面的形貌,能谱( EDS)计算出钙磷比( Ca/P)比。在5倍模拟体液中浸泡后,材料各表面均形成了分布和尺寸相对均匀的微米级(2~10 um)颗粒。其钙磷比接近羟基磷灰石,可以认为获得了比较理想的玉米蛋白-羟基磷灰石多孔支架复合材料。
為瞭提高玉米蛋白的骨誘導性和骨結閤性,以促進其在骨組織工程領域中的應用,將玉米蛋白多孔支架材料浸泡于5倍模擬體液(5×SBF)中,嘗試在不同的條件下對玉米蛋白多孔支架材料錶麵進行倣生礦化。通過場髮射掃描電鏡( SEM)觀察倣生礦化後多孔支架材料各箇錶麵的形貌,能譜( EDS)計算齣鈣燐比( Ca/P)比。在5倍模擬體液中浸泡後,材料各錶麵均形成瞭分佈和呎吋相對均勻的微米級(2~10 um)顆粒。其鈣燐比接近羥基燐灰石,可以認為穫得瞭比較理想的玉米蛋白-羥基燐灰石多孔支架複閤材料。

In order to promote the application in bone tissue engineering, the zein scaffold was soaked in a solution of 5 times the concentration of simulated body fluid (5 ×SBF) to enhance its bone inductivity and osseointegration.The field emission scanning elec-tron microscopy (SEM) was employed to observe the surface microstructures of the coating and energy dispersive spectrometer (EDS) which was attached to the SEM was used to carry out the elemental analysis and to calculate the ratio of calcium to phosphorus ( Ca/P) .The surface of the composite materials form uniform micro particles(2-10 um) that the ratio of calcium to phosphorus closed to that of hydroxyapatite (HA) after soaked in 5SBF.The zein-HA composite can be considered as an ideal material in bone tissue engi-neering.
