Atomic Resolution Electron Microscopy: A New Tool for Organic Chemists
Eiichi Nakamura, Professor of Chemistry, Department of Chemistry, University of Tokyo,

In February 2007, we reported movies of the conformational change of a single organic molecule recorded on an atomic resolution transmission electron microscope (TEM).[i]  This single-molecule atomic real-time TEM (SMART-TEM) movie of a single molecule provided the first demonstration of our ability to study the connectivity of carbon atoms and their time-dependent changes of single organic molecules and molecular clusters at atomic resolution.  Below are illustrated the frames of a movie of a biotin derivative attached to the tip of a carbon nanotube moving slowly in vacuum.[ii]  Fundamental science and applications will be discussed.
