Nanotechnology is a promising field, but also riddled with a lot of hype. Because the behaviour of materials at the nano-scale is quite different from bulk behavior, the properties of nanomaterials (particularly nanoparticles) are not always well understood and whats worse, do not always fit in with known theory so well.
So, extoll the virtues of nanomaterials by all means, but temper it with realism.;-)
Nanotechnology has the potential to impact the electronics/data storage industry the most in the short-medium term, for the medical side of things, we will have to wait a bit longer.
Had read about nanotechnology, but, i was really impressed by its ability to be used as concentrate contrast agent and anti-cancer drugs to improve imaging and treatment of cancer.
I work in a related field, and it is indeed promising, but see my statements above. Much of the behavior of these nanoparticles in-vivo is not well understood, and of the literature in the field, about 80-90% is junk, based on unreproducable empirical results.
We are atleast 5-10 years away from seeing nanoparticle based therapy systems result in a drastic leap over exisiting methods. Sure, small, incremental improvements are always going to be there, but for a big breakthrough, we need to wait a bit longer.
