So, ideally what we did see was, in fact, it does have enough energy with the UV lamp, it wasn't a dramatic shift you saw because we didn't start very high and then it went to that stuck point.

所以，理想上我们所看到的，事实上，紫外灯没有足够的能力，因为我们没有从非常高开始,所以它没有一个特别显著的移动,然后它又回到了黏着点。

So we can figure out the energy of each photon emitted by our UV lamp by saying e is equal to h c over wavelength.

所以我们可以计算出,每个从紫外光源射出的光子,也就是e等于h乘以c除以波长。

Nano bar codes are the molecular versions of traditional bar codes--metal nano-particles that have specific, recognizable chemical fingerprints that can be read by a machine, perhaps a UV lamp or optical microscope.
