Immobilization of enzymes on a nanocarrier can improve their stability, but is often accompanied by a reduction of the initial catalytic activity. Meanwhile, inevitable mass loss during centrifugal separation inhibits reusability. It is still a challenge to design and prepare an immobilized enzyme with both improved catalytic activity and reusability simultaneously.

CPO-Fe3O4 @ mTiO2纳米复合材料，具有集成的磁分离以及酶和光催化活性，可有效降解废水中的有机污染物

将酶固定在纳米载体上可以提高其稳定性，但通常伴随着初始催化活性的降低。同时，离心分离过程中不可避免的质量损失抑制了可重复使用性。设计和制备同时具有改善的催化活性和可重复使用性的固定化酶仍然是一个挑战。
