This follow-up paper, from the Journal of Nanotechnology Online, provides an in-depth look at the way poor countries engage with nanotechnology. It analyses why some developing nations are ahead of others in nanotechnology progress, and the challenges some less-developed countries face in shoring up nanotechnology capacity. It also investigates nanotechnology patent activity and assesses country participation in nanotechnology policy dialogues – for instance, China is a frontrunner in filing nanotech patents yet it is absent from policy discussions.
