The Cambridge Nanoscience Centre, home to Cambridge University's Nanoscience group, conducts research on nanowires and nanotubes, dielectrophoresis and nanometre-scale characterisation of electrical properties of conducting polymers.

Its website links to ongoing projects as well as upcoming and past seminars on topics including nanocrystals, self assembly of discrete structures and catalysis by nanogold. The website also hosts an image gallery of nanoscale pictures.

The CNS, based at Arizona State University in the United States, conducts research on the societal implications of nanotechnologies and engages policymakers and businesses in dialogue on these.

The centre publishes books, articles, presentations and reports on key topics and hosts a network of researchers developing and testing new processes of 'anticipatory governance' to understand and govern rapidly emerging areas of nanotechnology.

The CNS-UCSB serves as a network hub for researchers and educators working on the societal issues of nanotechnologies, including historical contexts, innovation processes and risk perception. It provides access to its research results, scientific papers, meeting reports, policy documents and presentations on a range of topics including water.

The centre publishes news on upcoming events and links to other US organisations working on nanotechnology.

The Desert Research Institute is based in Nevada in the United States. Its principal research areas include atmosphere, water and land management – in the United States and in the developing world. The institute is engaged in a project to bring clean water and sanitation to communities in Ghana, Mali and Niger through the West Africa Water Initiative (WAWI). WAWI aims to do this before 2008.

IBSA, a joint project of the departments of science and technology in Brazil, India and South Africa, promotes research collaborations between scientists working on applications of nanotechnology. Its priority fields of research include health, water treatment and agriculture. India leads its flagship project on water purification.

IBSA publishes information on participating scientists from all three countries, ongoing projects, key global events and activities, and fellowships and job openings.

The International Risk Governance Council recognises that nanotechnology can potentially lead to improvements in medical diagnostics and water treatment but argues that the use of this technology comes with significant human and environmental risks that are more complex and far-reaching than many other innovations.

In response to these risks, the council's nanotechnology project has developed a generic approach to risk governance that is summarised, together with key recommendations for action, in a White Paper and policy brief.

The Meridian Institute publishes daily summaries of news stories on nanotechnology for development, reporting on key innovations and technological applications, policy issues, risk-related information and technology transfer. While these stories cover a wide spectrum of disciplines — from health to materials to environment to agriculture — the institute also offers a compilation of water-related nanotech news summaries for those interested in the applications and implications of using nanotechnology for clean water.

The institute also runs projects and holds workshops on key issues — including the use of nanotechnology in water treatment — and publishes relevant background papers, presentations and case studies.

This online magazine publishes news and commentary on a range of nanotech applications from nanomedicine to nanotech for clean water. It also advertises jobs, book releases, events and links to nano art. In addition, Nano hosts an archive of country profiles outlining the state of nanotechnology including laws, advances and relevant companies.

NanoChina offers a range of information services on nanotechnology in China. They include: a news service, advertising for nanotechnology products, business networking opportunities in China and trade directories in English and Chinese, reports on nanotechnology developments in China and the rest of the world, event planning for conferences, meetings, workshops and visits taking place in China. NanoChina also offers a specialised translation service from Chinese to English and vice-versa for reports, articles, news stories, newsletters, press releases, advertisements, conference and marketing literature. NanoChina was launched in February 2006 by the U.K. based Institute of Nanotechnology.

Nanowerk is a clearing house for information about nanotechnology and nanoscience. It publishes regular news on key developments and a daily feature article — written in cooperation with scientists — looking at new findings, reviewing current research or exploring interesting applications such as water treatment.

Nanowerk also hosts a database of more than 1,900 nanomaterials and links to key events, reports, documents, magazines, organisations and blogs relevant to nanotechnology. Its video library links to dozens of animations and videos about nanotech research, speeches and lectures.

The Responsible Nano Forum is a non-profit charity that publishes information on the opportunities and risks presented by nanotechnology, aiming to improve public understanding of this subject and encourage public participation in the debate.

The forum runs public engagement programmes and hosts debates on the social and ethical issues of using nanotechnology.

SAFENANO publishes information on the health and environmental risks of nanoparticles, including the risks of waterborne nanoparticles. Its website provides daily news updates and feature articles as well as discussion boards and blogs for users to join in the debate. Background papers and guidelines are also available on key issues including risk management approaches.

The Project on Emerging Nanotechnologies, a partnership between the Woodrow Wilson International Center for Scholars and the Pew Charitable Trusts in the United States, is dedicated to minimising the possible risks of nanotechnologies as these technologies advance and ensuring public engagement in decision-making.

It publishes research results and meeting reports on topics such as agriculture and food, medicine and water treatment. The project also publishes news on its own projects and other key developments, and lists relevant events, mostly in the United States. A photo gallery provides access to images of some nano-based products and events.
