Risks are high on the agenda in our society, to the extent that we might refer to the society as a risk society. Our society experiences emerging technologies, like nanotechnology. Different actors respond to this in a variety of ways. Among these are the consumers, an important, but neglected category of actors in this context. Arguably it is in our role as consumers we first encountered nanotechnology, in the form of nano-enabled products at the consumers market. What consumers think and do, reacting to the mixed messages about benefits and risks of nanotechnology, contributes to how the risk society (with regard to nanotechnology) is developed, and in that sense becomes operationalized. The theme of this thesis is not just the responses of consumers (and how others perceive these) to the introduction of nanotechnology, but also a case study of how the risk society can be operationalized.
The study focused on the following questions: What do consumers know about nanotechnologies? How do they rate nanotechnologies? How do they obtain information? How would they like to be informed in the future? The results show that the "Nano-Hype" appears to be fading. Surprisingly, regarding the quality of the consumers' statements, e.g. how detailed their descriptions of the individual examples are, it can be said that their knowledge about all fields of application has decreased. Even though the knowledge about all fields of application has decreased, particularly striking is the decline in the fields of surface coatings, construction materials and environmental engineering. In sum, it can be hypothesised that consumer communication on the part of product manufacturers has decreased considerably, or that the information does not reach the target group to the same extent. The public knowledge on nanotechnologies has become more abstract.
In recent years billions of dollars have been invested in nanotechnology research. Nanotechnology is said to have such pervasive consequences that the 21st century is already proclaimed to become the 'nano-century'. Nanotechnology may also contribute to development in the global South. The new characteristics of nanotechnologies are also said to offer solutions for problems faced by people in the global South, especially in the fields of water, energy, and health. For instance water filters, energy storage systems, solar powered electricity and portable diagnostic tests may be developed and improved using nanotechnology. But the very same features that give rise to new opportunities may also generate new risks. There may be risks to the human body and environment. But for instance also investing in nanotechnology itself can be seen as a risk.
A group of experts from the chemical industry and various research laboratories in Germany have published a report on the current status of risk research on nanotechnology materials and applications. The report - 10 Years of Research: Risk Assessment, Human and Environmental Toxicology of Nanomaterials - provides an overview of the current state of risk assessment and toxicological research into nanomaterials. It also lists and summarizes the national and European projects on toxicology on various nanomaterials. In their report, the working group "Responsible Production and Use of Nanomaterials" has drawn up a list of topics and priorities which need to be addressed; activities and projects which have already been carried out; are currently on-going; or are still at the planning stage. The main focus of our considerations is on Germany, with a wider outlook on papers and results at European level.
Back in the early 2010s, food nanotechnology seemed to be a very hot topic and large industrial food companies were eager to explore new opportunities offered by nanotechnology applications. Then, as critical voices from NGOs and regulators appeared, the food industry went into silent mode. But that doesn't mean that food nanotechnologies aren't being researched and developed in labs around the world. Here is an overview of what nanotechnology applications are currently being researched, tested and in some cases already applied in food technology. It appears that we are still some way from seeing "Frankenfoods" in supermarket shelves. According to a recent commentary by an FDA official, what's holding back the introduction of nanofoods is the hesitation of the food industry, fearing a public backlash along the lines of what happened wit genetically modified foods.
Survey research indicates that religious belief will be a powerful influence in shaping public views about nanotechnology, while knowledge about nanotech will be less influential. And yet religious thought about nanotech has received little attention. We know that nanotechnology has evoked a large body of literature on moral and ethical issues, but almost all of this is expressed in secular voices, e.g., those of philosophers, ethicists, and scientists. Religious commentaries about nanotechnology have been much more rare. Now it is worth knowing what religious voices have said about nanotechnology, so that we might anticipate future religious reactions.
Engineered nanomaterials present regulators with a conundrum - there is a gut feeling that these materials present a new regulatory challenge, yet the nature and resolution of this challenge remains elusive. But as the debate over the regulation of nanomaterials continues, there are worrying signs that discussions are being driven less by the science of how these materials might cause harm, and more by the politics of confusion and uncertainty. Yet the more we learn about how materials interact with biology, the less clear it becomes where the boundaries of this class of materials called "nanomaterials" lie, or even whether this is a legitimate class of material at all from a regulatory perspective.
Patterns of news coverage on nanotechnology are developing in ways that mirror issue cycles for previous technologies, including agricultural biotechnology. In particular, early coverage of nanotechnology was dominated by a general optimism about the scientific potential and economic impacts of this new technology. This is in part related to the fact that a sizeable proportion of nanotechnology news coverage - at least in newspapers - continues to be provided by a handful of science journalists and business writers. This is an initial draft of an article that what will eventually become a chapter on public attitudes toward nanotechnology in a new book on risk communication and public perception of nanotechnology. It's meant to be a current update and comprehensive overview of what we know (and don't know) at this point.
