Capturing specific proteins from complex biological samples remains a significant challenge in medical research. Researchers recently made a major advancement in lysozyme capture technology by developing a hierarchical three-dimensional polymeric nanofibrous aerogel. This innovative scaffold allows for high-capacity and ultraselective capture of lysozymes.

Mechanisms of Lysozyme Capture Technology

The research team utilized 3-Aminophenylboronic acid (APBA) as a functional monomer. This monomer creates multimodal interaction sites that are essential for recognizing lysozyme. Consequently, the synergy of electrostatic interactions, hydrophobic forces, and π-π stacking leads to superior performance. Specifically, the aerogel achieved an adsorption capacity of 736.90 mg/g. This value significantly exceeds existing state-of-the-art adsorbents. Furthermore, the selectivity coefficient reached an impressive 4.17.

Preserving Antibacterial Potency

Practical utility was demonstrated through the extraction of lysozymes from raw egg white. Importantly, the process preserves the native conformational integrity of the enzyme. As a result, the extracted lysozymes exhibited potent antibacterial activity against Staphylococcus aureus. This finding is crucial because it confirms that the capture method does not compromise the protein's therapeutic potential. Additionally, molecular simulation methods verified the interaction mechanism at the interface of the imprinted polymers.

Conclusion

Overall, this research provides a feasible idea for designing highly selective adsorbents. Such advancements in protein separation could streamline the production of bioactive enzymes for clinical applications. Moreover, the study illustrates the power of multimodal interactions in molecular imprinting.
