When "Magic Nano" cleaning spray went on the market in March, it got yanked almost immediately after over 100 people reported coughing fits and breathing problems. So was this the first health disaster for nanotechnology? No, considering the product didn’t contain any nanotechnology or nanoscale particles, just a nano marketing ploy.
The product used the name because it created a thin film on the surface you were cleaning but didn't use any nanoscale properties. The problem with the product was more about a poorly tested traditional aerosol.
We should keep this story in mind as nanotechnology finds its way into more and more products. Nanotechnology product expert, Neil McClelland, puts it well when he says,
"People are just starting to hear about nanotechnology and this issue will just help to bring the issue to the fore. But it would be disastrous for all concerned if the nature of nano is destroyed. Imagine if we had had a bad batch of penicillin at the beginning and wrote it off - that would have been a tragedy. The implications of nanotechnology in healthcare are massive. We have a moral obligation that this technology will do well."
