“As we enter the 21st century, nanotechnology will have a major impact on the health, wealth and security of the world’s people that will be at least as significant in this century as antibiotics, the integrated circuit, and man-made polymers.”
-Interagency Working Group on Nanoscience, Engineering and Technology Report (1999)
