Transmission Electron Microscopy (TEM) is a technique which has proven indispensible in a range of scientific fields, including cancer research, materials science, virology, and semiconductor research. TEM, which has been around since 1931, allows users to examine specimen at a higher resolution than light microscopes. Grids are required to place specimen on, and traditional grids often have too large gaps for particularly small specimen, such as single atoms. Excitingly, graphene, a novel new nanomaterial, has found an application for use in TEM imaging.
