中央大學化學系謝發坤教授團隊開創「水相固相結晶」(SSC)策略,能在接近常溫常壓的水溶液中,像玩分子樂高般組裝出堅固的鋯「金屬有機骨架」(MOFs),並同步將酵素安全封裝,實現了「溫和製程中封裝活性生物分子」的目標,研究成果登上化學旗艦期刊《Angewandte Chemie- 德國應用化學》封面。

2025年諾貝爾化學獎頒給日本、美國、澳洲的三位科學家,表彰他們發明「金屬有機骨架」(MOFs)材料。這種結構規則的「奈米海綿」,擁有無數整齊孔洞,科學家能像組裝樂高般設計其孔洞特性,使其在吸附溫室氣體、氣體分離與氫能儲存等綠能領域大展身手。儘管潛力無窮,MOFs在生物醫學的應用仍是一大挑戰。

謝發坤教授團隊研究獨步全球,開創「MOF 化學生物學」新領域。團隊早期開發出溫和的「一鍋合成法」,能在不破壞生物分子的情況下,將嬌貴的生物酵素完整包裹在 MOF 中,如同打造「奈米防護殼」的保護層,保護酵素在工業催化或藥物傳輸時的活性。然而,如何合成最為堅固的「鋯基 MOF」成為最大挑戰。傳統合成需要高溫與有機溶劑等,這些苛刻條件會破壞任何脆弱生物分子。為克服這項瓶頸,謝發坤教授攜手蔡惠旭教授與上海科技大學台灣籍卓聯洋教授,共同開創「水相固相結晶」(SSC)策略,成功破解難題。

這項技術能在接近常溫常壓的水溶液中組裝出堅固的鋯基MOF,並同步將酵素安全封裝。過往受限於嚴苛的合成條件,鋯基MOF材料蛋白質藥物傳輸領域的潛力始終未能充分發揮。此機制能將酵素、藥物或其他生物活性物質包覆於鋯基MOF中時,透過掌握包覆物表面的酸鹼性質,提高包覆的成功率和活性物質的穩定性。科學家如今能在常溫常壓的水溶液中,將酵素穩固包覆於堅韌的鋯基 MOF 中,如同為其打造專屬的防護殼。

此技術為生醫應用開闢新途徑,也使高效生物催化劑的製造邁向實用化。把材料組裝的「萬用鑰匙」,未來亦有潛力延伸應用於稀土回收等綠色科技領域,將臺灣的研發實力轉化為解決全球稀土供應困境的關鍵力量。
 

A research team led by Professor Shieh Fa-Kuen of the Department of Chemistry at National Central University has pioneered a “solid-state crystallization in aqueous phase” (SSC) strategy, enabling the assembly of robust zirconium-based metal–organic frameworks (MOFs) in near-ambient aqueous conditions. This method allows enzymes to be safely encapsulated during the crystallization process, achieving the long-sought goal of protecting active biomolecules under mild synthesis conditions. The team’s findings were featured on the cover of the flagship chemistry journal Angewandte Chemie.

Professor Shieh’s team previously developed a mild “one-pot synthesis” method that preserves enzyme activity for industrial catalysis and drug delivery. However, synthesizing highly stable zirconium-based MOFs had been a major obstacle. To overcome this, Professor Shieh collaborated with Professor Tsai Hui-Hsu and Professor Chou Lien-Yang of ShanghaiTech University, jointly developing the SSC strategy to solve this long-standing problem.

This technique enables the formation of durable zirconium-based MOFs in near-room-temperature aqueous solutions while firmly encapsulating enzymes within the tough MOF structure. It paves a new path for biomedical applications, advances the practical use of efficient biocatalysts, and offers promising potential for expansion into green-technology domains such as rare-earth recycling.
