Two nanobots in pulmonary alveola killing a virus using nano-lasers.

Atomic structure of diamond. Carbon atoms are represented by spheres and their bonds by cylinders.

A small coral of atoms (blue, perhaps assembled using the tip of atomic force microscope) on an face-centered-cubic surface.

Atomic structure of graphene, a planar structure in graphite.

Top-down look at graphite. Neighboring graphene planes are colored differently (red and black).

Nanometric two-dimensional structures found in eyes of some insects (natural photonic crystal).

Artistic view of a zig-zag carbon-nanotube-like structure submersed in the sea. Reminiscent of the might of the constructions of Mother Nature.
