Selective functionalization of laser printout patterns on cellulose paper sheets coated with surface-specific peptides

Abstract

Printed and non-printed paper regions are selectively coated with surface-specific peptides, containing either direct functional peptide domains or maleimide to enable post-coating introduction of more complex peptide domains. To introduce specific functional domains onto paper based patterns, the light-controlled nitrile imine tetrazole ene cycloaddition (NITEC) approach is employed as a mild ligation technique. The strategy offers ready access towards the functionalization of paper based materials where structural patterns can be obtained via standard office laser printers.
