The smallest DNA 3D object, a triangular prism with only one turn on each edge, was constructed from a single-stranded DNA. We confirmed its structure using scanning tunneling microscopy. This work proves that single-stranded DNA can escape from kinetic traps to form stable topology.
最小的 DNA 3D 物体，一个每条棱上只有一个圈的三角棱柱，是由单链 DNA 构建的。我们使用扫描隧道显微镜证实了它的结构。这项工作证明了单链 DNA 可以摆脱动力学陷阱，形成稳定的拓扑结构。
