We report herein a new and enabling approach for decorating both living and abiotic surfaces with the extracellular matrix IKVAV peptide in a site-specific manner using strain promoted azide-alkyne cycloaddition. A cyclooctyne derivatized IKVAV peptide was synthesized and immobilized on the surface of pancreatic islets through strain-promoted azide-alkyne cycloaddition with cell surface azides generated by electrostatic adsorption of cytocompatible poly(L-lysine)-graft-poly(ethylene glycol) (PLL-g-PEG) copolymer bearing azido groups (PP-N3). Both “one-pot” and sequential addition of PP-N3 and a cyclooctyne derivatized IKVAV peptide conjugate enabled efficient modification of pancreatic islet surface in less than 60 min. The ability to bind peptides at controlled surface densities was demonstrated in a quantitative manner using microarrays. Additionally, the technique is remarkably rapid and highly efficient, opening new avenues for molecular engineering of cellular interfaces and protein and peptide microarrays.
