Abstract
Methods are provided for concentrating particles on the surface of a drop or bubble in a continuous phase, for separating different types of particles, and for removing particles from the surface of the drop or bubble. The methods also facilitate separation of two types of particles on a drop or bubble, optionally followed by solidification of the drop or bubble, to produce a particle for which the surface properties vary, such as a Janus particle. The methods can be also used to destabilize emulsions and foams by re-distributing or removing particles on the surface of the drop or bubble, facilitating coalescence of the particle-free drops or bubbles.
