Biocompatible metal organic framework material glutamic acid-zinc as well as preparation and application thereof

The invention belongs to the technical field of new materials and particularly relates to biocompatible metal organic framework material glutamic acid-zinc as well as preparation and an application thereof. The biocompatible metal organic framework material glutamic acid-zinc is obtained by dropwise adding a disodium glutamate to a Zn(NO3)2 methanol solution. The method has the characteristics that the production speed of glutamic acid-zinc crystals is high, the preparation condition is mild, the prepared product is good in crystal form and the like, can be applied to a series of amino-rich enzymes such as lipase, protease, epoxide and the like and has the potential of being used as a protein drug carrier. The product is added to an Aspergillus niger lipase phosphate buffer modified with EDC or EDC*HCl and NHS for oscillation immobilization, and immobilized Aspergillus niger lipase is obtained. The method is high in immobilization efficiency, high in enzyme activity recovery rate, convenient to operate, mild in condition and the like.
