各化学母质流向滚动中的金属或塑料基片的表面，他们互相作用，形成一层纳米级微粒网状结构。

As chemical precursors stream onto the surface of a rolling metal or plastic substrate, they react with one another to form a network of nanoparticles.

但Ro themund的目的不是做微型地图，Ro themund说，将来在使用金属或其他材料构造纳米结构时，微小的DNA结构可以作为支架使用。

But the real goal of this work isn't tiny maps. Rothemund says that in the future, tiny DNA shapes could serve as scaffolds for quickly building nanostructures made of metals or other materials.

为了预测金属会形成他们所寻找的纳米结晶质结构，Schuh博士和同事使用了把不同金属的原子混合一起的电脑模型。

To predict which metals would form the nanocrystalline structures that they were searching for, Dr Schuh and his colleagues used computer models that put atoms from different metals together.
