FUNDING:None Nanotechnology is a fast-growing scientific research area internationally and is classified as an important emerging research area. In response to this importance, South African researchers and institutions have also increased their efforts in this area. A bibliometric study of articles as indexed in the Web of Science considered the development in this field with respect to the growth in literature, collaboration profile and the research areas that are more within the country's context. We also looked at public institutions that are more active in this arena, including government policy considerations as guided by the National Nanotechnology Strategy launched in 2005. We found that the number of nanotechnology publications have shown a remarkable growth ever since the launch of the strategy. Articles on nanotechnology have been published in numerous journals, with Electrochimica Acta publishing the most, followed by Journal of Nanoscience and Nanotechnology. These publications fall within the traditional domains of chemistry and physics. In terms of the institutional profile and based on publication outputs over the period reviewed, the Council for Scientific and Industrial Research is a leading producer of publications in nanotechnology, followed by the University of the Witwatersrand -institutions that are both based in the Gauteng Province. There is a high level of international collaboration with different countries within this field -the most productive collaboration is with India, followed by the USA and China, as measured through co-authorship.
Significance:• Nanotechnology as a field of research is experiencing rapid growth and there is a need to understand progress from a South African perspective.
IntroductionInnovations linked to science and technology developments are believed to be promising contributors to economic progress internationally. In response to this promise, South Africa adopted the National Research and Development Strategy 1 in 2002 to enable the transition from a resource-based economy to a knowledge economy, which was followed by the Ten-Year Innovation Plan towards a knowledge-based economy 2 . This strategy was viewed as pivotal to the achievement of national goals, including enhanced economic growth, industrial competitiveness, as well as social and developmental aspirations.3 To this end, a number of targeted interventions and investments were made in specific fields of science, one of which was nanotechnology. Nanoscience and nanotechnology (N&N) is now widely recognised as an area of science and technology that promises to bring many scientific breakthroughs in the coming years, which will have a meaningful impact on the economy. According to Lux Research 4 , the revenue from nano-enabled products worldwide as of 2014 stood at USD1.6 trillion -a growth of 90% in 2 years from USD850 billion in 2012. The application of nanomaterials occurs in many industries such as cosmetics, construction and electronics. It is i...
