Nanotechnology and society: The evolution of risk perceptions

What do we now know about public perceptions of the risks of nanotechnology? What do we have good reason to expect about how those perceptions will evolve? A brief commentary, published in Nature Nanotechnology, addresses these questions. The commentary also identifies appropriate steps to extend investigation of nanotechnology risk perceptions and discusses the contribution this form of study makes to understanding of public risk perceptions and communication generally.
