    在組織工程研究中，如何在體外提供更仿生的環境，以培養出功能性的器官單位(如仿 肝小葉、腎元、胰島、骨單位等），一直是一個重要的研究主題。生物組織或器官是由 多種細胞外間質、適當排列細胞、與生長因子等結構性與階層性構成。近來許多團隊在 可交聯之水凝膠材料中培養細胞，以交聯後之三維結構的水凝膠扮演細胞外間質角色， 提供適當強度訊息、包埋生長因子以提供生化訊息，使細胞生理表現更優於二維培養之 結果。除此之外，可光交聯之水凝膠可調控三維結構之幾何形狀，而達到細胞因形狀而 自我排列、或幹細胞而分化之結果。然而要達成高結構性之仿生組織，現有技術仍有許 多需要突破之處，例如：（1)細胞在水凝膠中須更有、結構性的排列，而非隨意分布；（2) 複雜幾何形狀組織難以塑形，非光交聯水凝膠材料更難；（3)無法提供多種細胞/水凝膠 之任意組合與共養。 在本計畫中，我們提出以「通用電操控微流體平台」幫助以上目標之達成。過去我們已 在此平台上實現三大通用性：（A)通用液體電性(可驅動導電之電解液與介電之油等液 體）；（B)通用液體型態(可驅動微液滴、連續微流體、與任意形狀之液體）；（C)通用操控 尺度(可驅動液體與其中細胞或顆粒）。此計劃將此三大通用性應用於：（A)以介電濕潤或 介電泳產生各種導電特性之可交聯預聚物溶液之定量微液滴並操控之；（B)以介電泳任 意變形各式可交聯預聚物溶液以形成各種不同幾何形狀；（C)以介電泳排列細胞於可交 聯預聚物溶液並以介電濕潤或介電泳組合交聯前後預聚物溶液與水凝膠。進而達到本計 畫之三大操控目標：（1)細胞在交聯預聚物細胞溶液中排列與集中(尺度）；（2)各式可 交聯預聚物細胞溶液(包含熱交聯與化學交聯)之驅動與塑形(100 pm尺度）；（3)多種細胞 /水凝膠之任意組合與共養(cm尺度）。

    體外受精（IVF、或常稱為試管嬰兒）是二十世紀最令人振奮的科學發展之一，而此技術將持續對人類的生命有重大的衝擊。而IVF先驅者-Robert Edwards博士也於2010年榮獲諾貝爾生理醫學獎。人體IVF技術取代輸卵管之功能，而以人工方式，在一培養皿（Petri dish）中以礦物油覆蓋、且含有適當化學組成之靜態液滴（20 to 950 ml），進行胚胎授精、受精、培養。然而在輸卵管內，胚胎在著床前不但經歷化學（荷爾蒙）的刺激，更經歷物理的刺激。因此胚胎在輸卵管中的運動，合理地被視為與胚胎發展有關。人體IVF的受孕率，自1980年的16.5%提升至1983年近30%，而在2008年趨緩於8.8-47.6%（與年齡相關）。為增加IVF成功率，通常會植入多囊胚，然而此舉會增加多胞胎的危險。直到最近才開始有學者將仿生與微流體技術與IVF結合。微流體因與輸卵管有相似尺寸，因此可提供受精卵與胚胎更接近母體的物理與化學條件。因此以微流道為主的微流體技術已開始應用於精蟲處理、卵子成熟、受精、與胚胎培養。然而此研究尚屬開始階段，而有部份結果彼此矛盾。總的來說，許多研究結果得到較高之胚胎發展率，而將之歸功於營養物與廢物之有效循環；而將部份得到低胚胎發展率之結果歸咎於流體對胚胎之剪應力、與流體移除了必要的自體分泌之生長因子。因此將微流道之微流體技術應用於IVF，仍須更多研究之投入。因此我們提出動態的IVF（DIVF），以介電濕潤、介電泳等技術驅動一動態液滴，以期能在體外更模仿輸卵管。我們是第一個以數位微流體技術研究DIVF的團隊。而此微液滴技術將承襲過去幾十年來發展之IVF技術，但加上新的元素（動態），我們相信會比微流道技術有更強力的後盾。我們的目標為（1）發展數位微流體之模組化實驗室晶片系統，以（2）模仿並進行輸卵管中胚胎之授精、受精、與培養，（3）並即時診斷胚胎之發展狀況，而提升IVF成功率。並且，我們期望以此可擴充之模組，強化目前IVF所用microdrop法。以數位微流體技術，提供各式流體操控技術，以模仿體內如纖毛對胚胎之作用，並簡化重複之流體交換步驟。更期望以微小且定量之液滴，提高胚胎發展率，降低受精所需精蟲濃度。在此整合計畫中，我們在四個子計畫中進行四個重要工作：流體操控（子計畫一）；授精與受精（子計畫二）；培養與共養（子計畫三）；診斷與整合（子計畫四）。四個子計畫以適當之模組界面互相連結，並獨立且互補地進行。子計畫一提供基本流體功能驅動授精、培養液、檢測試劑等，並驅動胚胎與抗體修飾之微粒。子計畫二與子計畫三將在子計畫一準備好的定量水油比例之包覆式微液滴中，進行授精/受精與培養/共養。而子計畫二與子計畫三研究之受精卵與囊胚將以子計畫四之化學、物理、形態之診斷方式進行檢測。我們期望以此動態、仿生、回授控制之微液滴中，提高鼠與豬的胚胎發展率。
