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.

Gradient induced particle motion in suspensions

Methods described herein, in some embodiments, permit extraction of particle structural and/or surface charge data from gradient induced particle motion in channels. In one aspect, a method of manipulating particle motion comprises introducing a fluid into a channel, the fluid comprising particles, and driving particle accumulation to a preselected location in the channel by setting advective velocity of the fluid to offset diffusiophoretic mobility of the particles at the preselected location.
