Immobilization Techniques in the Fabrication of Nanomaterial-Based Electrodes for Biosensing

Immobilization procedures entail limiting/anchoring an entity (enzyme or cells) in or on an inactive reinforce/substrate material for strength, improved effectiveness, and simple component recoveries. Enzyme immobilization offers a fantastic foundation and increased operation stability by improving the catalytic characteristics of the enzyme. The immobilization of enzymes to a surface has been influenced by a variety of circumstances and a variety of different ways. Enzymes that have been immobilized can be used in a variety of operations. There are now numerous innovative methods for immobilizing enzymes that are more effective and widely used. The enhancement and ease of the propagation mechanism is apparent in the advancement of first to third generation biosensorsBiosensors. However, the use of nanotechnology in sensor alteration has been receiving more attention recently and provides a variety of benefits. The use of nanotechnology in the creation of catalytic biosensors has substantially increased their selectivity and overall performance. Due to these materials’ significant influence on the characteristics of the resulting catalytic system, the choice of support material chosen is critical to the immobilization process. Numerous inorganic, organicOrganic particles, hybrid, and composite materials can serve as stable, effective substrates for biocatalysts. A critical survey of the multiple techniques for immobilizing nanomaterialsNanomaterials on transducer surfaces and immobilizing enzymes on these species is beneficial and timely given the special and favorable properties of gold nanoparticles, grapheneGraphene, and carbon nanotubesCarbon nanotubes (CNTs) as applied to electrochemical biosensors. This chapter will highlight the physical and chemical methods of enzyme immobilization utilized in biosensors that employ nanomaterials like carbon nanomaterials, polymers, metal/metal oxide nanoparticles and organic/inorganic hybrid nanostructures.
