Materials scientists build a synthetic system with compartments like real cells
(PHYSorg.com Chemistry)

Polymer chemists and materials scientists have achieved some notable advances that mimic Nature, but one of the most common and practical features of cells has so far been out of reach-intracellular compartmentalization. It refers to the way many different organelles, vesicles and other `water-in-water` soft structures in the cell, contain and isolate chemical reactions and processes. It also lets reaction products be selectively shared with end users inside the cell.
