This technology seems utterly revolutionary and cutting-edge! yuhuu you touch on a very interesting point though - the scope for this technology to be used for evil. If nanotechnology is capable of being harnessed in such a way as to make it a weapon then this is extremely worrying - the micro-Antithesis of the nuclear bomb. (Small scale technology that could have similar genocidal outcomes.)
Obviously this technology does have a significant amount of 'good' uses. Also obvious is the fact that the cost of the technology is astronomical (no pun intended

) and it will probably be a long time - I'd say upwards of 25 years - before this technology becomes a deomestic possibility.
