STM image of organometallic structures formed when dosing phenyl diisocyanide (PDI) on a reconstructed Au(111) surface. The chains that originate at the gold atoms island indicated by the white dash line resemble the shape of a "Nano Spider". The molecules were dosed from a kundsen type source as described in the following link:
