Nanotechnology has enormous potential to change society. An estimated global research and development investment of nearly $9 billion per year is anticipated to lead to new medical treatments and tools; more efficient energy production, storage and transmission; better access to clean water; more effective pollution reduction and prevention; and stronger, lighter materials. And these are just a few of the more significant ways in which people are discussing using the technology.
It is science of the very. very small.
virtually any science that involves understanding the world at the atomic level.
starts with atoms and builds them up into components that you need, rather then whittling small components from larger objects.
Experts believe possible dangers of nanotechnology lie in how these tiny particles might interact with the environment, and more importantly, with the human body. Billions of dollars are being spent to incorporate nanoparticles into products that are already being marketed to the public; when this investment is compared to the the comparatively scant research into nanotech health issues, some scientists became concerned.
