Small‐scale synthetic motors capable of generating their own motive forces by exploiting the chemical free energy of their environment represent an important step in developing practical nanomachines. Catalytic particles are capable of generating concentration and other gradients that can be used to self‐propel small objects. However, the autonomous movement of catalytic nanoparticles by self‐generated forces is a relatively unexplored area in colloid and interfacial chemistry. This paper explores the potential of catalytically self‐generated forces for propulsion of small objects through fluids.
