Nanotechnology Vs. Mechanical/Chemical Engineer

[Platano]

Wasn't sure where to put this, but I can't decide between studying Nanotechnology or Mechanical/Chemical Engineer. Cost for schooling doesn't matter, but it is more of what each of the careers has to offer. I like Nanotechnology but I keep seeing that its use is broader than anything. Any insight on either of the majors would really help such as Avg Income, Kind of Jobs I could get, Opportunities I have with each.

Thanks
