There are two types of microscopy when it comes to observing atoms; atomic force microscopy (AFM) and scanning tunneling microscopy (STM). The former has proved to possess a very high resolution, surpassing the STM, due to the help of special sensors that are found in watches. This technology has allowed us, among other things, to measure forces that act in atomic manipulation or resolve structures within single atoms.
