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 and go from there.

Can anyone direct me to info on potential health and physical hazards
associated with nanotechnology (specifically nano-particles)? 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.
