Abstract
Methods of inducing or controlling particle motion in suspensions and colloids are described. In one aspect, a method of inducing particle motion in a suspension comprises contacting the suspension with a gas phase to establish at least one interface between the gas phase and continuous phase of the suspension. One or more gases of the gas phase are transferred across the interface to provide a solute gradient in the continuous phase, the solute gradient inducing motion of the suspended particles.
