DNA Makes Lifeless Materials Shapeshift (sciencemag.org)

sciencehabit writes: Researchers have engineered tiny gold particles that can assemble into a variety of crystalline structures simply by adding a bit of DNA to the solution that surrounds them. Down the road, such reprogrammable particles could be used to make materials that reshape themselves in response to light, or to create novel catalysts that reshape themselves as reactions proceed.

DNA is not eternal

What happens to the shapes when the DNA disintegrates? I presume that real organic DNA is being used here and that its removal leads to a return to chaos for the gold particles.
