Molecular cargo transportation is an ongoing and vital undertaking in every cell of the human body. However, Nature does not use wheeled vehicles to perform this task. Instead, Nature transports intracellular cargos using bipedal molecular motors that walk along a mesh of molecular filaments called cytoskeletons. By mimicking Nature, the development of artificial track-walking molecular motors (nanowalkers), can potentially open up a wide range of nanoscale applications.
