Nanotechnology products, processes and applications have the potential to make important contributions to environmental and climate protection by helping save raw materials, energy and water as well as by reducing greenhouse gases and problematic wastes. Great hopes are being placed on nano-technologically optimized products and processes that are currently under development in the energy production and storage sectors. Emphasis is often placed on the sustainable potential of nanotechnology, but this in fact represents a poorly documented expectation. Determining a product's actual effect on the environment - both positive and negative - requires considering the entire life cycle from the production of the base materials to disposal at the end of its useful life. Not every 'nano-product' is a priori environmentally friendly or sustainable, and the production of nanomaterials often requires large amounts of energy, water and environmentally problematic chemicals.

A commentary by Steffen Foss Hansen and Anders Baun in this week's Nature Nanotechnology pointedly asks "when will governments and regulatory agencies stop asking for more reports and reviews, and start taking regulatory action?" The two scientists take issue with yet another scientific opinion on nanosilver that has been requested by the European Commission in late 2011: "SCENIHR - Request for a scientific opinion on Nanosilver: safety, health and environmental effects and role in antimicrobial resistance". Specifically, the EC wants SCENIHR to answer four questions under the general heading of 'Nanosilver: safety, health and environmental effects, and role in antimicrobial resistance'. These questions, however, have already been addressed by no less than 18 review articles in scientific journals.

The Action Plan, presented by the EU Commission in 2004, envisioned integrating "the social dimension into a responsible technology development" and strengthening efforts related to "health, safety, environmental aspects and consumer protection". This encompassed (1) the systematic study of safety-relevant aspects at the earliest possible date, (2) integrating health- and environment-relevant aspect in research and development, (3) conducting targeted studies on toxicology and ecotoxicology and, finally, (4) adapting risk assessment approaches to nano-specific aspects in all phases of product life-cycles. The primary goal was to improve the competitiveness of European industry. The draft presented in mid-2011 for the planned research priorities2 continues this strategic focus. This article describes a selection of 22 current projects dealing with safety research as related to nanotechnology.

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.
