The STEHM Microscope: Finally, Nanoscientists Can See What They're Doing

Your average atom is about 62 to 520 picometers in diameter, but since that's a full factor smaller than the 390 to 700 nanometers human eye can perceive, direct observation using conventional microscopes is physically impossible.
