Here's a good reality check for how consumers perceive your nanotech research: this article from AlterNet looks at whether the benefits of nanotechnology make up for the risks. Even though nanoparticles are continuously popping up in more and more consumer goods -- they're found in everything from sunscreens and cosmetics to air fresheners and shoe liners, the article writes -- reports have linked them to toxicity in both humans and fish. While the US spent $1.4 billion on nanotech R&D last year, only 1 to 4 percent was given to risk assessment. "We are part of an experiment," says George Kimbrell, an attorney for the International Center for Technology Assessment.
