Abstract
Unidirectional mechanical motion of nanoobjects along an interface can result from highly nonequilibrium processes which transmit the energy from various external sources to the system. Phenomena of this kind underlie the operation of so-called Brownian (molecular or biological) motors and have been attracting a great research interest in the last few decades. This chapter presents the main necessary conditions for directed motion of nanoparticles along the surface under the action of external nonequilibrium fluctuations; the methods to realize such conditions are also considered. Several examples are given for high-efficiency Brownian motors, molecular pumps, photoinduced molecular motors, and dipole rotators (the latter rotate unidirectionally in a linearly polarized alternating electric field).
