Abstract
The present application relates to a vehicle whose shell material is modified with at least one additional secondary phase that acts as a cork. In the presence of an energy source (preferably ultrasound), the corks embedded in the shell are either removed from the shell to create permanent pores or perturbed within the shell to create transient pores that can control transport in or out of the vehicle.
