It takes place in a desert city (Mojave, I think) - there is nanotech, a fair amount of dystopia, genetic modification, and I think someone sprouts wings in the end...kind of cyberpunk-ish.

3This is very, very generic. You are almost asking "There were spaceships, I think". Please attempt to come up with more details, they need not be from the story itself... time period written (or read), length, style (young adult, etc). – John O Feb 19 '13 at 20:07
If you take out the "someone sprouts wings in the end", I would say you are describing Prey by Michael Crichton. Published in 2002, it is described thusly in wikipedia:
The novel serves as a cautionary tale about developments in science and technology; in this case, nanotechnology, genetic engineering, and artificial intelligence.
