An enzyme/metal-organic framework (MOF) composite with both highly stable and easily reusable features was prepared via tethering enzyme/MOF nanocrystals with polydopamine (PDA). The micrometer-sized PDA tethered enzyme/MOF composite can be easily repeatedly used without obvious activity loss, promising for efficient enzymatic catalysis at low cost with long-term operational stability under harsh conditions.
通过用聚多巴胺（PDA）连接酶/MOF纳米晶体，制备了一种兼具高稳定性和易于重复使用特性的酶/金属有机框架（MOF）复合材料。微米级的PDA连接酶/MOF复合材料可以很容易地反复使用而没有明显的活性损失，有望在苛刻条件下以低成本实现高效酶催化，并具有长期操作稳定性。
