Book excerpt: This volume demonstrates how cellular and associated electron microscopy contributes to knowledge about biological structural information, primarily at the nanometer level. It presents how EM approaches complement both conventional structural biology (at the high end, angstrom level of resolution) and digital light microscopy (at the low end, 100-200 nanometers). Basic techniques in transmission and scanning electron microscopy Detailed chapters on how to use electron microscopy when dealing with specific cellular structures, such as the nucleus, cell membrane, and cytoskeleton Discussion on electron microscopy of viruses and virus-cell interactions
