The device scans employees' hands for contamination each time they wash and can detect gut biomolecules in just seconds.

该设备可在员工每次手扫描其双手是否受到污染，并能在几秒钟内检测出肠道物分子。

Exactly how this happened is not known, but it involves biomolecules, molecules like DNA which are found in living things.

这到底是如何发的尚不清楚，但它涉及物分子，像在物体内发现的DNA这样的分子。

We're talking about uncovering entirely new biomolecules.

我们正在谈论发现全新的物分子。

As a result, the biomolecules were able to keep their natural shape.

结果，物分子能够保持其自然形状。

So one kind of biomolecule might get a blue color. Another kind of biomolecule might get a red color.

所物分子可能会变成蓝色。另物分子可能会变成红色。

Various biomolecules in saliva absorb light at the same wavelength— but each has a distinct chemical fingerprint.

唾液中的各物分子吸收相同波长的光，但每都有不同的化学指纹。

And these molecules could react and start a sort of a reaction chain that would eventually lead to something like a biomolecule.

这些分子可反应并启动反应链，最终产类似物分子的东西。

But the organic molecule that seems to be at the center of the chemical networks that can produce biomolecules is hydrogen cyanide.

但似乎处于可产物分子的化学网络中心的有机分子是氰化氢。

Ice is not a biomolecule, but when it mixes with carbon, the atoms in ice molecules change to produce complex molecules – and that's when interesting things start to happen.

冰不是物分子，但当它与碳混合，冰分子中的原子会发变化，产复杂的分子，——然后有趣的事情就开始发了。
