The creation of a molecular structure involves “atom-to-atom” “assembly” under appropriate physical conditions and rate.
Laser ablation is one possible avenue to create man-made materials. E.g., from graphite:
Fullerenes and Carbon Nanotubes
Amorphous Carbon (Films)
Carbon Nano-Foams
Granular low density nanofoam: TEM image shows the free-standing fractal structure of the carbon foam. The foam consist of a network of interconnected carbon clusters of ~ 6nm in size
