Abstract
Purpose: This study examined the need for public communication about nanotechnologies and nanoparticles by providing a comparative analysis of the differences in risk awareness of nanotechnologies and nanoparticles between consumers and experts. Methods: A total of 1,007 consumers and 150 experts participated in this study. A questionnaire was prepared examining their awareness of nanotechnologies and nanomaterials and their view of the necessity for information and education about the latest nanotechnologies and nanomaterials. Results: Our results indicated that the expert group recognized that they knew more than consumers about nanotechnology and that there was a need for relevant education in nanotechnology and nanomaterials among consumers. We found that the consumer group had a more positive attitude toward nanotechnology, even though they did not know much about it. Moreover, the consumer group was inconclusive about the type of information on nanotechnology deemed necessary for the public, as well as the suitable party to be responsible for education and for delivering the information. Conclusion: An education and promotion program targeting consumers should be established to overcome the differences between consumers and experts in their awareness of nanotechnology. Specifically, the establishment of concepts for nanomaterials or nanoproducts is required immediately. With clear standards on nanomaterials, consumers can make informed decisions in selecting nanoproducts in the market.
