Hi, I am writing an essay on (the possible risks of) nanotechnology, and one of the assignments is to analyze the alternative techniques available. I honestly can't think of any..?! I suppose I could write about the different techniques nanotechnology improves or replaces, but there are so many small things to write about and not just one large subject, and we only need to use about 300 words so I'm going to have to choose subjects at random, and to be honest I have no clue which I should choose... The whole assignment does not seem to make sense to me, at least not for the subject of nanotechnology. I mean, if I were writing about electrical cars for example, well sure, the alternatives are fossil fuel, hydrogen fuel etc... Quite easy to compare those techniques. But for nanotechnology??? I chose the subject nanotechnology myself, the choice is free for everyone so maybe I just made it hard for myself lol... Can anyone think of anything sensible I can say about any alternatives of nanotechnology..? Thanks!
