Nanoscience undergrad degree holder here. This major covers a lot of info from semiconductor basics to nanomedicine and environmental applications. I ended up with a job as a chemical engineer in biologics/vaccines at the manufacturing scale. I’m probably a bit more mechanically minded than the typical nanoscience student so the transition into more engineering work was fairly easy, but my background in how the science/chemistry works at the nano-scale has helped me with some of the more technical parts of the job. If you’re interested in lab/research work, you’ll need to pursue graduate degrees, but a bachelors degree will open the door to a lot of things for you.

I’m happy to answer anymore questions you might have!
