从那时起，Seeman和其他一些化学家开始向人们展示他们可以用DNA来构造极微小的东西。例如，比头发细1000倍的立方体和八面体。

Since then, Seeman and other chemists have shown that they can use DNA to build really simple shapes such as cubes or octahedrons that are 1, 000 times thinner than a human hair.

即使在冰融化后，也几乎总会残留一些这种四面体，如100个分子那么宽的微小冰立方体。

Even after ice melts, some of those tetrahedrons almost always remain, like tiny ice cubes 100 molecules wide.
