  • Title: Covalent immobilization of active lysozyme on Si/glass surface using alkoxy Fischer carbene complex on SAM.
    Author: Dutta P, Ray N, Roy S, Dasgupta AK, Bouloussa O, Sarkar A.
    Journal: Org Biomol Chem; 2011 Jul 21; 9(14):5123-8. PubMed ID: 21629886.
    Abstract:
    A cross-metathesis reaction between an alkene terminated self-assembled monolayer (SAM) on glass/Si wafer and an alkene tethered Fischer carbene complex yielded a functionalized surface. Rapid aminolysis of the Fischer carbene moieties permit efficient anchoring of amine containing molecules on such a surface. Attachment of 1-pyrenemethylamine was thus monitored by ATR-IR spectroscopy and fluorescence microscopy. Similarly, BSA and lysozyme were individually grafted to such Fischer carbene modified surfaces using their pendant lysine residues. It has been demonstrated that the anchored lysozyme retains its bactericidal property.
