Topologically controlled DNA catenanes are promising elements for the construction of molecular machines but present a significant effort in DNA nanotechnology. We report an efficient approach for preparing linear three-ring catenanes (L3C) composed of single-stranded DNA. The linking number was strictly controlled by using short complementary regions (6 nt) between each two DNA rings. Read More
