Nanoscale folding of DNA: Taking advantage of facile solution processing, pattern formation under light irradiation, and ready chemical modification of graphene oxide, various patterned films of chemically modified graphene were prepared and employed for spatial patterning of DNA origami structures (see picture). The patterning of DNA origami structures required highly selective adsorption on graphene oxide surfaces.
