ABSTRACT
Degradable Newkome-type and polylysine dendrons functionalized with spermine surface units are used to control the formation of DNA origami structures. The intact dendrons form polyelectrolyte complexes with the scaffold strands, therefore blocking the origami formation. Degradation of the dendron with an optical trigger or chemical reduction leads to the release of the DNA scaffold and efficient formation of the desired origami structure. These results provide new insights towards realizing responsive materials with DNA origami.
