From medGadget:

At the London Centre for Nanotechnology, a project organized by University College London and Imperial College London, researchers developed novel nanoscale drug delivery vesicles that can be designed to selectively release only certain cargo.

The vesicles are polymersomes, tiny bubbles made of a stable polymer, that contain embedded DNA nanopores within their membranes. The nanopores are made of self-assembling DNA strings and can be tuned to form into a cylindrical shape having a hole of a predefined size.
