I moved the list of individuals to List of nanotechnology topics, I think it belongs better there. Antony-22 00:34, 24 November 2006 (UTC)

ancient nanotech!

I am not happy with this: "Humans have unwittingly employed nanotechnology for thousands of years, for example in making steel and in vulcanizing rubber. Both of these processes rely on the properties of stochastically-formed atomic ensembles mere nanometers in size, and are distinguished from chemistry in that they don't rely on the properties of individual molecules." Any comments? Sangak 18:35, 27 February 2007 (UTC)

The idea is that there are often claims that nanotechnology dates back to the Middle Ages or even before that since stained glass gets its color from metal nanoparticles, although obviously they didn't know anything about nanoparticles. It's really a stretch to call that "nanotechnology," but people persist. This seems to be along the same lines, but it's even more of a stretch than the stained-glass thing. I'd be OK with removing it. Antony-22 09:16, 6 March 2007 (UTC)

this is a very much advanced source and this this this is a very much useful in the future as many long jobs can make short arun from tamilnadu

National Nanotechnology Initiative

The National Nanotechnology Initiative and the role of Mihail Roco in it should be mentioned in this article. Without this initiative we wouldn't have such widespread use of nanotech today. —Preceding unsigned comment added by 86.106.53.43 (talk) 09:13, 31 October 2010 (UTC)

Article massively expanded

I have expanded this article by assembling text from the articles There's Plenty of Room at the Bottom, Norio Taniguchi, Eric Drexler, Scanning tunneling microscope, Atomic force microscopy, Richard Smalley, Carbon nanotube, Why the future doesn't need us, Molecular nanotechnology, Molecular assembler, National Nanotechnology Initiative, Implications of nanotechnology, and Nanotechnology. Turns out there was a lot of material on the history of nanotechnology on Wikipedia, it was just scattered among a lot of different articles... Antony–22 (^talk⁄_contribs) 06:42, 12 May 2011 (UTC)

Did NASA invent ferrofluid?

Is ferrofluid the first nano-engineered material that was designed at the nano scale? ```` — Preceding unsigned comment added by Electricmic (talk • contribs) 30 March 2012‎

Timeline

Will somebody add a timeline? This would be immensely useful! — Preceding unsigned comment added by 168.190.66.63 (talk) 16:23, 14 May 2014 (UTC)

Early use

This section should be expanded.
nanoparticles were used by

• the Damascans to create swords with exceptionally sharp edges
• Romans to craft iridescent glassware (Lycurgus Cup )
• a corrosion resistant azure pigment known as Maya Blue
• iridescent metallic glaze called lustre
• possibly Iron pillar of Delhi

By modern-day standards, they were working in a branch of nanotechnology called nanocomposites.[1][2]

Mosfet fuff and all that

I completely fail to see what introduction of mosfet has to do with nanotechnology. The source [[3]] says nothing about nanotechnology at all. The claim that: "In 1962, Atalla and Kahng fabricated a nanolayer-base metal–semiconductor junction (M–S junction) transistor that used gold (Au) thin films with a thickness of 10 nm" is referenced to [[4]]. Again no mention of nanotechnology whatsoever, in fact according to Pasa, Atalla and Kahng weren't even the first to do it!. The rest of Nanoscale transistor section is just complete mess, and I fail to see what's the significance of this development for nanotechnology. I am going to remove this section all together. DMKR2005 (talk) 21:08, 5 February 2021 (UTC)

Nanoelectronics, nanoscale transistors, Moore's law and MOSFET scaling down to nanoscale levels all fall under nanotechnology. When you're using transistors that are only a few nanometers in size, that's nanotechnology. Nevertheless, I've taken your complaints into account and re-written some parts of that section, like removing most of the Atalla and Kahng stuff, and mentioning Rose and Geppert before them.
