When you're building nanostructures, the position of each and every atom counts. After all, that's one of the factors that determines, for example, whether a material will be a semiconductor or an insulator, or whether it will start up a process or stop it. But our current imaging techniques aren't precise enough yet to give us full control over nanomaterials. Researchers are working to combine tools we have with new approaches to the data they yield to develop atom maps. Pretty cool.
