Nanophobia (fear of nanotechnology)

This article in the New York Times discusses the fear of nanotechnology and the possible safety issues associated with this new field of science.
Should we be afraid? Can nanoparticles inadvertently cross the barrier of our skin? Would they accumulate in organs if they can't be metabolized?

I would like to hear from people working in this exciting new field. Are these fears justified?
