使用表面修飾石墨烯電極於缺氧環境之溶氧感測及其在3D生物反應器運用

為了解決SENS FDA的問題,作者王竣生 這樣論述:

近年來,生物反應器被研究並使用於藥物篩檢領域,傳統的二維(2D)細胞培養,因具有細胞單層的特性,缺乏許多體內存在的環境特徵,然而在實際的癌症腫瘤環境中,存在不均勻性且不受控制的氧氣微環境,對於現有的細胞培養領域是一個重要的問題,因此需要開發三維(3D)細胞培養技術以達成其產業需求,且應用於癌細胞培養領域亦需要能監測低溶氧區間之感測系統。本研究開發一應用於低溶氧之微流體環境的可撓式溶氧感測器,以克拉克式三電極為基礎建立,使用聚對二甲苯(Parylene)作為底材,以氧氣電漿製程進行石墨烯材料之表面處理製作具官能基團石墨烯混合液,將一部分混合液添加奈米銀粒子(AgNPs),並以抽氣真空過濾法分別

製成三電極後,轉印至基材上,再對含有AgNPs之電極進行電解以建立AgCl參考電極,完成官能化石墨烯/官能化石墨烯/氯化銀之三電極後,以Nafion塗覆於最上層做為固態電解層與選擇性薄膜。使用生物相容性之聚對二甲苯作為基底材與封裝材,可避免於生物應用中的細胞排斥現象,且此電極具可撓性,可完整貼附於微流體環境中,利於監測癌細胞培養環境的氧濃度。首先,實驗驗證使用之石墨烯材料與其官能化的特性,進行材料化學態分析並探討與相對濃度之Nafion電解質的修飾特性,並於易控制的簡易生物反應器環境中進行電極的設計與感測器性能比較,最終利用電化學檢測在自製的PDMS微流道環境中驗證石墨烯電極溶氧量測,以得到生
