Abstract
Enzymes, as biocatalysts, possess the characteristics of high efficiency, specificity, and environmental friendliness in industrial production; however, their applications are restricted by issues such as poor stability, high cost, and difficulty in recovery. To address these challenges, enzyme immobilization technology has achieved significant progress in recent years, becoming a crucial strategy to enhance enzyme performance and economic feasibility. This study systematically reviews the latest developments in enzyme immobilization techniques, including covalent binding, physical adsorption, cross-linking, and encapsulation, while thoroughly investigating the mechanisms by which different immobilization methods influence enzyme activity, stability, and reusability. Additionally, this paper analyzes the advantages and potential limitations of various novel carrier materials, such as nanoparticles, me tal-organic fr amework materials, and porous silicon, in enzyme immobilization. By comparing the performance metrics of traditional and modern immobilization technologies, it was found that dynamic immobilization methods based on smart responsive materials can significantly improve enzymatic catalytic efficiency and adaptability, demonstrating broad application prospects. Furthermore, this article evaluates the practical application potential of enzyme immobilization technology in fields such as food processing, pharmaceutical manufacturing, textile dyeing, and environmental remediation, proposing feasible pathways to optimize immobilization schemes to meet specific industrial requirements. The study indicates that a multiscale design strategy combining computational simulation with experimental validation can further promote innovation and development in enzyme immobilization technology. Overall, this research not only summarizes the core advancements in current enzyme immobilization technology but also clarifies future research directions, providing essential references for the industrialization of enzymatic catalytic processes.
