Alternative approaches are required if nanotechnology is to boost global health and equity, argues social scientist Donald Maclurcan.

In developing countries nanotechnology for health should improve living conditions, not just treat disease, says Guillermo Foladori.

Regulating nanotech is challenging, says Rajender Varma, but green chemistry could help developing countries 'leapfrog' to cleaner, healthier products.

Nanomedicine requires careful development, not a great rush to jump on the bandwagon, argues nanotech expert Manoj Varma.

Nanotech in hygiene, fake drug detection and remote diagnosis will do more for health than nanodrugs, says Mohamed Abdel-Mottaleb.

Nanotechnology's potential to improve public health will be maximised only with a conducive environment, argues Jayashree Vivekanandan.

Nanotechnology must be effectively shared with stakeholders if it's to deliver clean water, say Thembela Hillie and Mbhuti Hlophe.

Engineering a useable product is the key to making nanotechnology work for water treatment, says Ashok Raichur.

Emerging nanotech for purifying water at this stage should be regulated with existing laws, say Malini Balakrishnan and Nidhi Srivastava.

Nanotechnology should be used to develop Cuban pharmaceutical products to prevent them being pushed out of the market, warns an expert.

Technology transfer is central to translating nanotechnology research into benefits for society, says Bai Chunli.

A group of researchers from the University of Toronto, Canada, argue that the debate on nanotechnology is failing to consider possible benefits for developing nations.
