Facile Immobilization of Enzyme via Co-Electrospinning: A Simple Method for Enhancing Enzyme Reusability and Monitoring an Activity-Based Organic Semiconductor

The stability, reusability, and monitoring of enzyme activity have been investigated to improve their efficiency for successful utilization in a broad range of industrial and medical applications. Herein, we present a simple method for fabricating an electrospun fiber/enzyme scaffold via co-electrospinning. The characterization of soluble and immobilized α-amylases with regard to pH, thermal stability, and reusability were studied. An organic light emitting material tris­(8-hydroxyquinoline)­aluminum was incorporated to monitor the enzyme activity for several reuses.
