Propelling single molecules in a controlled manner along an unmodified surface remains extremely challenging because it requires molecules that can use light, chemical or electrical energy to modulate their interaction with the surface in a way that generates motion. Nature’s motor proteins have mastered the art of converting conformational changes into directed motion, and have inspired the design of artificial systems such as DNA walkers and light- and redox-driven molecular motors.

Nanoscale systems designed to imitate functions from the macroscopic world lead to a new appreciation of the complexity needed to actuate motion at the limits of miniaturization. A nanoscale 'car' is

A chiral molecular propeller designed for unidirectional rotations on a surface

A surface-adsorbed molecular propeller that, upon excitation with a scanning tunneling microscope tip, can rotate clockwise or anticlockwise depending on its chirality, and directly visualize its stepwise rotation with STM images.

This work pioneered the use of a new, stable and tunable molecular rotor system based on surface-bound thioethers to comprehensively study many aspects of molecular rotation and culminated in the first experimental demonstration of a single-molecule electric motor.

It is shown how the rolling of a single molecule equipped with two wheels can be induced by the STM tip, and the approach of controlling the intramolecular mechanics provides a path towards the bottom-up assembly of more complex molecular machines.

Directional control in thermally driven single-molecule nanocars.

It is shown that the observed movement of the nanocars is a new type of fullerene-based wheel-like rolling motion, not stick-slip or sliding translation, due to evidence including directional preference in both direct and indirect manipulation and studies of related molecular structures.

A rack-and-pinion device at the molecular scale.

This work presents a molecular rack-and-pinion device for which an STM tip drives a single pinion molecule at low temperature, functioning as a six-toothed wheel interlocked at the edge of a self-assembled molecular island acting as a rack.
