What major do I need to do in order to become a nanobiotechnologist? Oh, and is it worth doing? or is it very risky?
Chemistry seems to be the best path for nano-related work. A 2016 Nobel Prize for nano research was awarded under Chemistry:

A few US universities offer nanotechnology as an undergraduate major, but it’s more commonly a field for grad study. IMO, the trendiness of nanotechnology doesn’t appear to have generated a commensurate number of jobs.
It’s not a chemistry field. It’s not a field that falls nearly under any single larger field of study but is instead quite interdisciplinary. Chemistry, physics, and various forms of engineering all have involvement.
I took a nanotechnology class once, and it was taught by a guy with a PhD in materials science. But it does seem to be interdisciplinary.
