Abstract
氫氧基磷灰石(Hydroxyapatite,HA)具有與人體及動物骨骼,成份、密度極為相近的材料,在相關的醫療文獻中也證明具有優異生物活性,對於細胞及骨細胞的引導及增長,而HA會隨時間將解至完全被吸收與代謝,且不會釋出金屬離子影響生物體。
氫氧基磷灰石(HA)粉末靶材與正方晶氧化鋯基材藉由基礎物性分析、微觀分析,藉此探討分析等基本性質來選定我們所需之氧化鋯燒結參數,為濺鍍基材所使用。
本篇碩論使用自製的氫氧基磷灰石作為濺鍍靶材,由射頻磁控濺鍍法,沉積於正方晶氧化鋯基材,藉著控制實驗鍍膜的參數,針對高頻入射的濺鍍功率100W、200W、300W兩小時,可以成功得到0.2~1μm的氫氧基磷灰石。
利用物性分析及微觀分析,來了解氫氧基磷灰石(HA)在薄膜中結構、成份及性質。最後薄膜進行骨母細胞實驗,並探討其生物相容性之影響。
實驗結果顯示自製HA靶材磁控濺鍍於氧化鋯基材,隨濺鍍瓦數的提升薄膜其性質與成份接近於氫氧基磷灰石,且具有較高的氫氧基磷灰石結晶、薄膜的厚度及粗糙表面輪廓有利於細胞引導及披覆。最後氫氧基磷灰石薄膜針對骨母細胞實驗分析驗證,在經24hr的骨母細胞實驗中可以發現磁控濺鍍300W時骨母細胞的披覆量較其他濺鍍功率具有較佳的生物相容性。
