Risk communication is critical in enabling public engagement with new technologies (balancing of technology benefits versus risks)
Forms the cornerstone of opinion-forming process on the public acceptance/debate regarding a given technology – has a lasting mark on the development of technologies and their applications
Should reflect current and dynamic social, scientific, and political imperatives
For nanotechnologies – its promises and potential public fears needs to be taken into account, and addressed expeditiously
Requires an on-going debates among different stakeholders to ascertain opportunities and risks (government, industry and the public)
But who remains the most suitable to communicate technology risks?
