DNA origami under different conditions relevant for materials science applications. (A) Adsorbed DNA origami at room temperature (left), at 150 °C (middle) and 250 °C (right) [102]. (B) Adsorbed DNA origami triangles before (left) and after 5 min exposure to UV/ozone (right) [103]. (C) Cross and bowtie DNA origami shapes are transferred from folding buffer (FOB) to H₂O (low-μM Mg²⁺ concentrations) and spray-deposited onto substrates [107]. (D) Graphene encapsulation protects immobilized triangular DNA origami from exposure to H₂O [109]. (A) is reproduced with permission from Ref. [102]; copyright American Vacuum Society 2014.
