目前有几项常规的方法被用于制造金微粒，但多数都会涉及在液态下使用到溶解的氯金酸（又称金盐）及添加化学品以沉降金原子。

There are several ways to produce gold particles, but most involve dissolving chloroauric acid, also called gold salts, in liquid and adding chemicals to precipitate gold atoms.

这种改进的技术包括下列三个步骤：利用增强的X射线显示出藏匿的物品、利用传感技术搜寻危险化学品，并利用无线射频技术识别液态和固态物质。

There are three main approaches: enhanced x-rays to spot hidden objects, sensor technology to sniff dangerous chemicals, and radio frequencies that can identify liquids and solids.
