What the potential hazards are is mostly a matter of speculation at this point. There is not even consensus on how airborne nanoparticles should be measured (by weight, by number, etc), whether skin contact is more or less of an issue than with macroparticles and many other basic concepts. I would begin with the NIOSH topical page on Nanotechnology at http://www.cdc.gov/niosh/topics/nanotech/ and go from there.

Our research group is presently looking into experimenting with nano-materials incorporating zinc, silicon and gold for use in the semiconductor and LCD industry. They mentioned interest in 'many more' nano-substances. Any input in this area would be greatly appreciated. Regards, I.
