What can /sci/ tell me about nanotechnology?

Is it really the future of mankind's technology?

Nano is big but I am also not sure as to how much,

Genetic tech, 3D/bio printing and AI tech are all the future of mankind that will grow exponentially equal to that of the industrial revolution however.

Crazy times ahead indeed.

But nano probably is as big?

Look at yourself
Realize that you probably only consist fo small atoms which are forming incredibly organized bonds with different properties (DNA, neuronal network, etc...)
>Nanotechnology is the future, as an organized state brings forth better properties than an unorganized state of the same material
>Unless we find a better method to self-organize materials, of course

Nanotech is just an umbrella term to cover ANY technology that has developed an atomic or molecular resolution, which is pretty much everything from material science, to genetic engineering, to microbiology, to solid state physics, to quantum optics, etc, etc..

As another anon mentioned, being able to control the states at this level of resolution opens up far more possibilities than relying on bulk properties of a material.

The key here, however, is self-assembly. There are a ton of awesome 'proof of concept' papers being published where scientists achieve incredibly remarkable results, but they do it by tedious manipulation (for example molecular beam epitaxy) which is time consuming and horribly expensive. If you cant automate things and scale it up to industrial level production, chances extremely high its not going any where as a technology. Thats what self assembly is all about, we want 'shake n bake' methods where we can dump ingredients in in bulk, and the align themselves under the proper conditions.

But still, nano is huge. If you like a very broad scientific background and some exciting applications and future opportunities, nano is definitely a solid education/career choice.

To be fair, MBE is used at the industrial scale in for some applications, but many of the proof of concept papers do push the limits. A better example is perhaps Atomic Force Microscopy (AFM) which can be used to push atoms around individually. IBM has some papers out which started with them resolving molecules and atoms, moved to them doing silly things like spelling their logo out with fluorine ions, and is now culminating with them building simple quantum bits.

The latter is an example of something which is profoundly useful and equally as expensive, with no method of self assembly on the immediate horizon. It is likely the Pentagon is working with IBM to finance and produce a working quantum computer (if they havent already), but the cost (and applications) put it firmly in the territory of State Property only.

I want to study robots at the nanoscale
I can't really find anywhere to study what is called "nanorobotics" in my country (denmark)
are there any other names for what I want to study?

What's the big deal with nantechnlogy? It's just extremely small computers chips inside people that releases chemicals.

for anyone interested in what this guy's talking about

http://www.cs.duke.edu/courses/cps296.5/spring06/papers/WMS91.pdf

this will be difficult to read without knowledge of chemistry

great paper that describes the challenge in designing nanostructures that self-assemble (technically we would call it an "entropically driven" process)\

[Anonymous No.6496793]

>>6496777
can you please explain these challenges?

[Anonymous No.6498371]

>>6495942
there is no such thing.
however you can study nanoelectronics. or try your hand at simpler devices (molecular motors, etc) but nanoscale robots is an oxymoron

[surrealdeal No.6498380]

it's a lot like senator stevens' view of the internet

[Anonymous No.6498749]

>>6498371
yeah, I realise that it'll take time to reach a point where nanorobotics is a thing but I was thinking - something that'll prepare me to work with those things. Thanks for the help

[Anonymous No.6498816]

Yes it's the future.

Here's how a basket of about 30 nanotechnology stocks I put together in 2012 performed over the year.

New technologies are actually creating proven profit streams, especially in the realm of materials and drug delivery systems.

I agree that the sector is inflated. But what else is going to be driving economic growth in the long term besides tech?

Do you guys think studying condensed matter physics could be a good choice to enter in the nanotech industry?

[Anonymous No.6498886]

Definitely.

Du skal bare læs nanoscience ved KU eller DTU. Men som sagt, nanorobotics er noget vrovl. Det tætteste du kommer er biofysik-molecular dynamik, hvilke er jo en del af nanofagene.
