It mixes small precursor particles of the different materials to create a "nanoparticle ink" that is continuously coated onto metal foil and then heated so that the particles assemble correctly.

它的生产过程是将不同元素的前驱粒子混在一起制成“纳米微粒墨”，将其连续不断地涂在金属薄片表面，然后通过加热处理使粒子适当地组合。

As the liquid evaporated, the ink became richer in gold, the fluid flowed over the holes, and a single nanoparticle of gold dropped into each one.

随着液体的蒸发，墨水的含金量也就随着增多，而当流体流过模板上的小孔时，一个单一的黄金纳米颗粒就会进入小孔内。
