A comprehensive review on enzyme immobilization techniques and their applications in biotechnology

In a number of sectors, such as pharmaceuticals, food production, and environmental control, enzyme biotechnology is essential. Enzyme immobilization, which involves binding enzymes to solid supports, improves their stability, reusability, and efficiency. This review focuses on this procedure. The article examines the various techniques for immobilizing enzymes, including adsorption, covalent bonding, entrapment, and encapsulation. Each technique has special benefits, including improved process control, decreased contamination, and better stability. In pharmaceutical applications, immobilized enzymes are frequently utilized for high-purity active pharmaceutical ingredients (APIs), drug manufacturing, and enzyme-based drug delivery. The article also emphasizes their function in vaccine manufacture and biosensors for disease diagnostics. It also looks at how immobilized plant and bacterial cells can be used for environmental applications such as bioremediation, biotransformation, and the synthesis of secondary metabolites. Enzyme immobilization's overall importance stems from its capacity to maximize industrial processes, making them more economical, efficient, and sustainable. Enzymes continue to provide creative answers to a variety of biotechnological problems through a variety of immobilization approaches.
