A basic walking molecule, aka “molecular walker”, based on non-interlocked architecture, shown with a passing-leg walking mechanism, which in principle can “choose” (Leigh, 2015) between alternative pathways.[1]

In terms, walking molecule (CR:5) (LH:6) (TL:11) is a molecule with legs, e.g. kinesin, DTA, AQ, or human, that has the ability to move bipedially along a surface, tube, or structure.


In 2005, Ludwig Bartels, German-born American physical chemist, at the University of California Riverside, designed a molecule, called DTA, or 9,10-DiThioAnthracene (Ѻ) molecule, with a body made of linked benzene molecules and two sulfur atom legs, which when cooled down to -223°C they form rows (Ѻ) and began to move in a straight line, walking on a flat copper Cu(111) surface, induce by a little heat, like a little human.
