This video segment adapted from Pennsylvania College of Technology and WVIA examines nanotechnology, the art and science of manipulating and rearranging individual atoms and molecules to create useful materials, devices, and systems. Learn how atoms are at the core of nanotechnology and how researchers are working to understand both the structure and behavior of atoms in order to develop revolutionary new products and applications in medicine and beyond. The video also expresses some of the safety concerns related to nanotechnology.
