In-cell molecular sieve from protein crystal
(PHYSorg.com Nanotechnology)

Scientists at Tokyo Institute of Technology, RIKEN, and Kyoto Institute of Technology have applied rational crystal design to create protein crystals with extended porous network to accumulate exogenous molecules inside living cells. This work lays a foundation for engineering of stable self-assembling crystalline porous materials which can concentrate and preserve bioactive substances in various cell types.
