Self-Assembly of DNA Double-Double Crossover Complexes into High-Density,Doubly Connected,Planar Structures

摘要

In 1993,Fu et al.described the double crossover (DX) DNA complex consisting of two DNA double helices connected by two reciprocal exchanges (crossovers).In 1998,Winfree et al.used DX complexes to self-assemble regular planar structures.Subsequently,several other DNA complexes have been designed and used to self-assemble organized structures.
