Nanotechnology is sweeping the world. This science of very small particles, which includes genetic modification and the reconfiguring of the arrangement of atoms, presents possibilities beyond imagination. It also has huge implications for all South Africans, especially at home.

How exactly is this new technology playing out in South Africa? In countries like India, nanotechnology is being supported as a source of income and innovation. It has the potential to improve both the human condition and a country's productivity and competitiveness.

Is South Africa doing what it should and could to foster nanotechnology and biotechnology, and to advance bioeconomies within the country? And what does the new technology mean for us as consumers? How many of us know that this technology is already being employed in substances like suntan cream and lipstick, with potential health implications for users?

The application of nanotechnology poses risks as well as huge benefits, so we need to be particularly vigilant of the ethics and dangers of it. This book provokes discussion around these important topics and relays eyeopening information to those of us who thought all of this was sci-fi.
