1. A method of inducing or affecting particle motion in a suspension comprising:
contacting the suspension with a gas phase to establish at least one interface between a gas phase and aqueous-based suspension continuous phase, the aqueous-based suspension continuous phase comprising one or more additives selected from the group consisting of protic species, polar aprotic species, ionic species, and mixtures thereof;
transferring one or more gases of the gas phase across the interface to provide a solute gradient in the continuous phase, the solute gradient inducing or affecting motion of the suspended particles.
