Held fast : Enzymes have been immobilized by the strong interaction between the Lewis acid sites on a La‐MCF support and the free lysine amino groups of PGA. The immobilized PGA has both high specific activity and enhanced operational stability. This approach opens up possibilities for developing innovative immobilized enzyme catalytic systems with high stability.

将镧掺入介孔二氧化硅泡沫中可增强酶的固定性，并由于路易斯酸与碱的相互作用而增强了青霉素G酰化酶的活性。

快速持有：通过La‐MCF支持物上的Lewis酸位点与PGA的游离赖氨酸氨基之间的强相互作用，固定化了酶。固定的PGA具有较高的比活和增强的操作稳定性。这种方法为开发具有高稳定性的创新型固定化酶催化系统提供了可能性。
