Nanotechnology is the creation, manipulation, and exploitation of materials with at least one dimension ≤100 nm. For only a few decades now, thanks to advances in microscopy, manipulation, and materials synthesis and deposition, scientists and engineers have been able to purposely create, control, and characterize materials at this scale. These scientific and engineering advances have led to the realization of some of the phenomenological explorations highlighted by Richard Feynman in his famous lecture, “There’s Plenty of Room at the Bottom.”1
