A video on the health and safety implications of nanotechnology. The health impacts of nanotechnology are the possible effects that the use of nanotechnological materials and devices will have on human health. As nanotechnology is an emerging field, there is great debate regarding to what extent nanotechnology will benefit or pose risks for ...
The term is sometimes expanded to also include nanotechnology's health and environmental impact, but this article will only consider the social and political impact of nanotechnology. As nanotechnology is an emerging field and most of its applications are still speculative, there is much debate about what positive and negative effects that ...
Ethics of nanotechnology is the study of the ethical issues emerging from advances in nanotechnology and its impacts.. According to Andrew Chen, ethical concerns about nanotechnologies should include the possibility of their military applications, the dangers posed by self-replicant nanomachines, and their use for surveillance monitoring and tracking.

Worldwide investment in nanotechnology increased from $432 million in 1997 to about $4.1 billion in 2005. [3]: 1–3 Because nanotechnology is a recent development, the health and safety effects of exposures to nanomaterials, and what levels of exposure may be acceptable, is not yet fully understood.
Effects vary widely over aquatic and terrestrial environments as well as types of organisms. [13] The characteristics of the nanoparticle itself plays a wide variety of roles including size, charge, composition, surface chemistry, etc. [ 14 ] Nanoparticles released into the environment can potentially interact with pre-existing contaminants ...
Nanotoxicology is the study of the toxicity of nanomaterials. [1] Because of quantum size effects and large surface area to volume ratio, nanomaterials have unique properties compared with their larger counterparts that affect their toxicity.
"Why the Future Doesn't Need Us" is an article written by Bill Joy (then Chief Scientist at Sun Microsystems) in the April 2000 issue of Wired magazine. In the article, he argues that "Our most powerful 21st-century technologies—robotics, genetic engineering, and nanotech—are threatening to make humans an endangered species."
Despite the current early developmental status of nanotechnology and molecular nanotechnology, much concern surrounds MNT's anticipated impact on economics [36] [37] and on law. Whatever the exact effects, MNT, if achieved, would tend to reduce the scarcity of manufactured goods and make many more goods (such as food and health aids ...
