Enzyme Immobilization: An Overview on Nanoparticles as Immobilization Matrix

Razi Ahmad and Meryam Sardar*

Immobilization process is to optimize the operational performance of an enzyme for industrial applications. So far different matrices have been described in the literature to improve the performance of the immobilized enzymes. With the advent of nanotechnology, the nanomaterials because of their unique physico-chemical properties constitute novel and interesting matrices for enzyme immobilization. The nanomaterials possess ideal characteristics to equilibrate principal factors which determine biocatalysts efficiency, including specific surface area, mass transfer resistance and effective enzyme loading. This review presents the current scenario and techniques in enzyme immobilization. An overview of the main methods used to combine proteins/enzymes with nanoparticles is given in the study. The advantages and disadvantages of nanoparticles as immobilization matrix are also discussed.
