A Molecule Carrier

Extending on our previous research on "walking molecules", we present the "Molecule Carrier": anthraquinone molecules diffuse not only linearly on Cu(111), they are also capable of attaching up to two CO2 molecules in a reversible fashion, thereby guiding these otherwise random diffusing molecules along one line. Loaded down, anthraquinone diffuses slower; every attached molecule roughly adds once the anthraquinone diffusion barrier.
