This chapter described the advancements in the development of nanostructured supported material and enzyme immobilization techniques. The functionalized nanomaterials extremely affect the inherent mechanical properties and provide the highest biocompatibility and specific nano-environment surrounding the enzymes for improving enzymes stability, catalytic performance, and reaction’s activities. The enzyme immobilization on nanomaterials considerably enhances the robustness and durability of the enzyme for its frequent applications, which reduces the overall expenses of the bio-catalytic process. There are various types of nanomaterials i.e. metal nanoparticles, metal oxide, carbonaceous materials (carbon nanotubes, graphene, and activated carbon), that have been used for the immobilization of the enzyme. So that durability, catalytic activity, leaching of the enzyme, and mechanical steadiness are evaluated for their continual operation.
