So what's a gold nanoparticle. Would it be a small bit of gold. I had to deal with a small bit of something recently too. This video leaves me underwhelmed, and I'm as sciencey-boffin as the next man. Lacuna in the information-to-audience presentation, methink, unless I'm just out of my depth here... here, on Youtube. Out of my depth on Youtube.
I'll just go & shoot myself.
Goodbye.

No, those are two little pieces of matter . I think (thow I'm not sure) ,at the end, the structures that are visible (the patterns) are the crystal structure of the metal ( the arranged gold nuclei ) , which is amazing.

what do we see at 1:26 - 5nm ... it looks like 2 Atoms bond together?
-
@wyvernlord23 No, the wavelength of the electrons here is a thousand times smaller than that. The two limits to getting good resolution of the gold here is the aberration in the lenses (it's far harder to make a perfect magnetic lens than a perfect optical lens), and that the gold nanoparticle is sat on a carbon film that is itself tens of nanometres thick, which you're also having to look through.

@TheFounderUtopia The worst is that he is not the only one who understood it seriously.

It's depressing that you needed to explain that to someone.
-
No, those are diffraction lines, though they are created by atoms.
-
WOW! So at the end are those lines atoms?
-
Does the resolution start to degrade at the 5nm mark because it is reaching the wavelength of the electron?
-
@zomgerln Haha sure

They could have even a better zoom using a webcam and CSI's image enhancement softwares...

@BogoblinGamer Yeah, I know. I was just making humor about webcam's low-quality pictures and CSI's exaggerated image enhancements. Saying that both could give a better result than a state of the art transmission electron microscope. Get it?
