Drawing on search-engine data gained from combining the term 'nano*' with the title of every
economy recognised by the World Bank, the research to be described here highlights a widespread developing
country engagement with nanotechnology research and development. Subsequent investigation reveals that the
orientation of developing country engagement is distant from nanotechnology's 'social development' applications,
often cited as most applicable to developing countries. The ability of less-developed countries to engage with
nanotechnology R&D is explored along with current mechanisms to facilitate partnerships and access to
information. The additional analysis of health-related patents confirms that the 'nano-divide' is already here.
With China constituting the bulk of patents from the South, the divide is not just between the developed and
developing world, it extends to within the developing world. An assessment of participation in international
nanotechnology policy and dialogue highlights low levels of developing country representation, supporting the
overall argument that nanotechnology may be set to follow the path of past technologies in creating a greater
global technological divide.

Based on the statistical result from ESI, all the journal articles published by TOP20 international institutions
in the field of chemistry were downloaded from the WEB OF SCIENCE. By using these data and performing statistics,
the author analyzed three kinds of co-occurrence phenomenon including institute-institute, institute-keyword, and
keyword-keyword (co-word). The discussion also referred to how to use bibliometrical methods to identify research
collaboration net, potential collaboration opportunity among these institutes and research fronts they devoted in.
