Ever since micro- and nano-technology first appeared, there has been a steady strive on the part of researchers to develop ways of manipulating structures formed at such small scales. The efforts have grown considerably once experts have started realizing that nanostructures – billionths of times smaller than the width of a human hair – are the future of electronics and maybe even medicine. Now, in a new National Science Foundation (NSF)-funded study, researchers at the Pennsylv....
