DESCRIPTION:Abstract: Many recent experiments address synthetic colloidal 
 particles capable of self-propulsion in the presence of a fuel supply. Unl
 ike passive Brownian motion which it superficially resembles\, their activ
 e motion breaks time-reversal symmetry. This allows unusual physics to ari
 se\, such as a liquid-gas phase separation among particles with purely rep
 ulsive interactions. In several systems\, the self-propulsion effect can b
 e switched on and off using a light field. I will discuss how these elemen
 ts might one day be harnessed to create self-rectifying microfluidic devic
 es under optical control\, and present 'proof of concept' simulations of t
 he basic effect.\n
