Electron microscopes are proving themselves indispensible tools in the world of nanotechnology. In this brief overview, we explore the potential of electrons within in situ transmission electron microscopy (TEM) with the electrons provided either from the imaging electron beam or from electrical currents across contacted specimens to nanoengineered graphene based on work at our labs. The use of electrons is demonstrated to be enormously versatile to pattern, heal, and even fabricate graphene. In essence, electrons provide a useful engineering tool box that with further development will enable device fabrication and modification inside a TEM, thus allowing one to study structure–property relationships of graphene as well as other low dimensional materials in near real time with atomic precision.
