The basic premise behind nanoscience is that manipulating individual atoms and molecules makes it "possible to build machines on the scale of human cells or create materials and structures from the bottom up with novel properties." This rather useful website from the National Science Foundation offers a great primer on nanoscience, complete with answers to basic questions like What is nanoscience? On the website, visitors can make their way through answers to this question and others via illustrative graphics, helpful descriptions, and short video clips. Near the bottom of the homepage, visitors will find areas like Nanoscience Discoveries. This area contains information about recent news from the field, such as work being done to create additional resources for those who rely on prosthetic devices and limbs.
