Abstract:
In this work, we are going to introduce a brilliant double enzyme microsystem prepared from co–immobilization of glucose oxidase (GOD) and glucoamylase (GA) on silver dendrites hierarchical (Ag–DHN) nanostructure. In this line, silver dendrites nanostructure was facilely synthesized using Raney nickel as the template and reducing agent at room temperature and ambient pressure. Then, glucose oxidase (GOD) and glucoamylase (GA) on Ag–DHN through multi-component reaction in water as green solvent. The success preparation of the unique biocatalyst system was confirmed by XRD, TEM, FE–SEM and BET analysis. The properties of free and immobilized enzymes were investigated and compared.
