Figure 7

Left figure: schematic showing the concept of a “ nano-mosquito ”; three-legged beetle-type robot with a nanopipette. The design of the nano-mosquito is inspired from the beetle STM developed by Besocke. The quote “Learn from nature and create what is not in nature” is by Dr. Heinrich Rohrer who invented STM. See Ref. [79] for more details on the nano-mosquito. Lower figure: conceptual image of the nano-mosquito reduced to the millimeter scale. Both illustrations were partly prepared by Miyuki Miyata.
