What are Jobs Involving Nanotechnology Today?

There is already work in nanotechnology, but it is not necessary for the job you really want.  

About the Industries

The solar industry now uses nano-particles to block UV radiation. The flat panel industry uses quantum dots to reissue the ultraviolet radiation in visible wavelengths. The bulb industry is also going to use quantum dots for the same reason. The digital camera industry to use quantum dots to absorb visible wavelengths and re-emit in the infrared, so the PV industry. The nanotubes are making a comeback in metallurgy as the secrets of Damascus steel is reinvented. 

As you can see

There are Plenty of jobs that involve nanotechnology, but it is a progression of jobs that existed in the field rather than a sudden onset of jobs that did not exist before.
