Thermal stability of DNA origami on mica.

The authors report the unusual thermal stability of deoxyribose nucleic acid (DNA) origami when adhered to a solid substrate. Even when heated to 150 C for 45 min, these DNA nanostructures retain their physical and chemical integrity. This result suggests that DNA origami could be integrated into applications requiring moderate substrate heating, such as photoresist baking or chemical vapor deposition processes.
