Juelich researchers take a look inside molecules

For their look into the nanoworld, the Juelich researchers used a scanning tunneling microscope. Its thin metal tip scans the specimen surface like the needle of a record player and registers the atomic irregularies and differences of approximately one nanometre (a billionth of a millimetre) with minuscule electric currents. However, even though the tip of the microscope only has the width of an atom, it has not been able so far to take a look inside molecules...
