Abstract

Patterns of the protein streptavidin on DNA origami are printed onto a functionalized surface. The streptavidins are linked to DNA via a disulfide spacer and these conjugates self-organise into a predetermined pattern on DNA origami. The structure immobilises on a biotin-SAM-functionalized Au surface. By disulfide cleavage the origami is separated from the streptavidins, leaving the protein pattern at the surface.
