Description

The technique of confining/anchoring enzymes or cells in or on an inert support for their stability and functional reuse is referred to as immobilisation of enzymes or cells. Enzymes are made more efficient and cost-effective for industrial use by using immobilized technique. Immobilized the enzymes maintain their structural conformation, which is required for catalysis. An immobilised enzyme movement in space has been completely or partially restricted. The process of confining enzyme molecules to a solid support over which a substrate is passed and converted to products is known as enzyme immobilisation. Reusing enzymes for multiple reaction cycles reduces the overall cost of enzymemediated reactions. Capability to quickly stop the reaction by removing the enzyme from the reaction solution. Physical adsorption, ionic and covalent bonds, and various techniques such as binding, entrapment, encapsulation, and cross-linking are all used to immobilize enzymes. Enzymes can be immobilised on a variety of organic and inorganic materials.

Enzyme immobilisation is a technique that is specifically designed to limit an enzyme's freedom of movement. Immobilization of enzymes is a common practice, primarily to reduce enzyme costs on the process economics by allowing the enzyme to be reused many times, as well as to reduce operation costs because the immobilisation technique may modify the enzyme behavior, lowering enzyme and product costs significantly. In this section, compare and contrast the fundamental properties of all immobilisation methods.

The benefits of immobilised enzymes

• Function is more stable and efficient, and it can be reused multiple times.

• The products are enzyme-free, making them ideal for multi-enzyme reaction systems.

• Controlling enzyme function is simple, making it suitable for industrial and medical applications.

• Reduce effluent disposal issues, increase enzyme substrate ratio, reduce reaction time, and use enzyme continuously.

Immobilization techniques

Entrapment immobilisation: The term "entrapment immobilisation" describes the capture of enzymes within a polymeric network or microcapsules of polymers that let the passage of the substrate and product.

Physical adsorption: Physical adsorption is the simplest technique for immobilizing enzymes. The process involves combining an aqueous solution of an enzyme with a support material that has adsorptive qualities at the suitable circumstances, and then separating the insoluble material by centrifugation or filtration after an acceptable amount of incubation. The solid is subsequently rinsed to remove any remaining unadsorbable particles.

Covalent immobilisation: A well-known chemical immobilisation technique used to create enzymatic biosensors is the covalent immobilisation of enzymes to polymeric substrates. Enzymes are conjugated to antibodies by creating a strong, covalent bond between the two.
