本研究利用PDMS立體流道搭配表面光嫁接技術,開發了泛用型W/O/W雙重乳化裝置,適用於多種極性與黏度各異的流體組合,可成功製作具生物可降解特性的薄殼載具。在流道設計上我們考慮了雙重乳化機制中介面力與黏滯力對結構成形與穩定的影響,並透過立體流道搭配表面光嫁接技術加以實現。其中立體流道是由多層PDMS結構接合而成,而表面光嫁接技術則可局部改變流道壁面親疏水特性。我們將生物可降解性材料溶解於有機相的乙酸乙酯中,先生成W/O/W雙重乳化結構,當乙酸乙酯逐漸被萃取出後,殘餘的材料將濃縮固化成薄殼狀結構。實驗證明W/O/W雙重乳化結構的內外徑尺寸可分別由最內與最外層水相流速獨立控制,分布在30至200μm與100至400μm的範圍內。利用這項裝置我們已經成功的製作三酸甘油脂、聚乳酸、及微脂體這三種薄殼載具,並能將磁性粒子鑲嵌於薄殼結構中,使其具備磁性導引與加熱釋放的特性。以此裝置所製備的薄殼載具擁有高包覆體積比、高穩定性、生物可相容性、及可控制運動與釋放特性等優點,可望應用於藥物包覆與釋放、細胞培養、以及生醫相關的各項基礎研究。
