"Smart" chemistry and its application in peroxidase immobilization using different support materials

Area of Science:

• Biocatalysis and enzyme engineering
• Materials science for bio-applications
• Surface chemistry and functionalization

Background:

• Enzyme immobilization is a key strategy in biocatalysis, enabling automation and high-throughput applications.
• Immobilization enhances enzyme activity and stability compared to free enzymes.
• Support matrix properties (particle size, mechanical strength) are critical for immobilized enzyme performance.

Purpose of the Study:

• To present a state-of-the-art review on the "smart" chemistry of enzyme immobilization.
• To explore novel potentialities of various materials-based cues for immobilization.
• To discuss the chemistry viewpoint of enzyme immobilization, often lacking in current literature.

Main Methods:

• Review of literature on enzyme immobilization techniques and materials.
• Focus on "smart" chemistry approaches and functional group involvement (amino, thiol, carboxylic, hydroxyl, epoxy).
• Discussion of diverse support materials including microspheres, hydrogels, membranes, nanoparticles, and nanofibers.

Main Results:

• Immobilization offers advantages like convenient handling, easy separation, and reusability of enzymes, particularly peroxidases.
• Diverse materials (nanoparticles, nanofibers, hydrogels, membranes) and geometries enhance enzyme performance.
• Various chemical strategies (click chemistry, amine, thiol, carboxyl, epoxy chemistry) are employed for surface functionalization.

Conclusions:

• Smart chemistry and advanced materials offer powerful routes for engineering highly active and stable immobilized enzymes.
• The review highlights the importance of understanding the chemistry of immobilization for rational design.
• Future applications can benefit from tailored enzyme immobilization strategies using novel support materials.
