Area of Science:

• Materials Science
• Biochemistry
• Analytical Chemistry

Background:

• Selective protein extraction is crucial for diagnostics and therapeutics.
• Developing efficient and reusable materials for protein separation remains a challenge.

Purpose of the Study:

• To prepare and characterize a novel magnetic ionic liquid surface molecularly imprinted polymer (Fe3O4@VTEO@IL-MIPs).
• To evaluate its efficiency for the selective extraction of lysozyme (Lys).

Main Methods:

• Synthesis of Fe3O4@VTEO@IL-MIPs using an imidazolium-based ionic liquid.
• Characterization using FT-IR, TEM, DLS, TGA, and VSM.
• Lysozyme quantification via UV-vis spectrophotometry and structural analysis using CD spectra.

Main Results:

• The Fe3O4@VTEO@IL-MIPs exhibited successful imprinting polymer layer formation.
• Maximum adsorption capacity of 213.7 mg g-1 and an imprinting factor of 2.02 were achieved.
• The material demonstrated high selectivity and stability in separating lysozyme from complex mixtures and real samples.

Conclusions:

• The developed magnetic ionic liquid imprinted polymer is a promising material for selective lysozyme extraction.
• Its high adsorption capacity and reusability make it suitable for practical protein separation applications.
