In 1959, Richard Feynman asked the question, "What would happen if we could arrange atoms one by one the way we want them?" Today, the emerging fields of nanoscience and nanotechnology are enabling control of the material world at the scale of atoms and molecules. Nanotechnology is inherently interdisciplinary and allows for new approaches to research and education through interdisciplinary connections between many fields including chemistry, physics, biology and materials science. This broad interdisciplinarity contributes much to the novelty of this new field, and will likely cause widespread change in the way science is pursued in the 21st century. This presentation will provide a glimpse at some of today's hottest nanoscience and nanotechnology developments including the instrumentation that allows us to 'see' or image individual atoms as well as the preparation of many types of nanoparticles and their applications. Lastly, this presentation will explore some of the potential ethical and environmental implications of nanoscience and nanotechnology.
