Microcapsules Ejecting Nanosized Species into the Environment

In this communication we report on microcapsules which eject nanoparticles into the environment. The speed of the nanoparticles ejected in water is similar to 800-fold faster than their Brownian diffusion. Such microcarriers may allow nanosized species to travel long distances, in short times, through highly viscous environments and may find applications in e.g. drug delivery and tissue engineering.
