Protein molecules were directly embedded in metal-organic frameworks (MOFs) by a coprecipitation method. The protein molecules majorly embedded on the surface region of MOFs display high biological activities. As a demonstration of the power of such materials, the resulting Cyt c embedded in ZIF-8 showed a 10-fold increase in peroxidase activity compared to free Cyt c in solution and thus gave convenient, fast, and highly sensitive detection of trace amounts of explosive organic peroxides in solution.
通过共沉淀法将蛋白质分子直接嵌入金属有机骨架(MOFs)中。主要嵌入在 MOFs 表面区域的蛋白质分子表现出很高的生物活性。作为这种材料的强大功能的一个例证,嵌入 ZIF-8 中的 Cyt c 与溶液中的游离 Cyt c 相比,过氧化物酶活性提高了 10 倍,从而方便、快速且高灵敏地检测溶液中痕量的爆炸物有机过氧化物。
