The original report indicated that one of the reactions she had was to her earrings. This suggests that previously she had had no reaction to the nickel in the earring posts, so the sensitization does appear to be related to the material being in nano form.
Just a guess.

The report is based on a single case and the fact that the symptoms arose after work with Ni nano-particle began; she had previously worked with non-nano Ni. For a particular incident, I'm not sure how you would determine whether the nano aspect exacerbated the situation. It's more of a suggestive data point report than a conclusive study...
