Fluids with an intrinsic gradient, for example in their temperature, charge, or density distribution, are known to produce a directed drift in suspended colloidal particles. This phenomenon is called phoresis. In this talk, I will summarize some recent theoretical work with the main focus on thermophoresis, mostly performed by means of mesoscopic simulations. These studies have also allow us to propose new applications in the design of promising phoretic machines such as microswimmers, turbines, or micropumps.
