Heat tolerance of DNA origami structures has been improved about 30 degrees C by photo-cross-linking of 8-methoxypsoralen. To demonstrate one of its applications, the cross-linked origami were used for higher-temperature self-assembly, which markedly increased the yield of the assembled product when compared to the self-assembly of non-cross-linked origami at lower-temperature. By contrast, at higher-temperature annealing, native non-cross-linked tiles did not self-assemble to yield the desired product; however, they formed a nonspecific broken structure.
