Article Correctness Is Author's Responsibility: Self-healing DNA nanostructures

(American Chemical Society) DNA assembled into nanostructures such as tubes and origami-inspired shapes could someday find applications ranging from DNA computers to nanomedicine. However, these intriguing structures don't persist long in biological environments because of enzymes called nucleases that degrade DNA. Now, researchers have designed DNA nanostructures that can heal themselves in serum. They report their results in ACS' journal Nano Letters.
