Sponge-like spheres give RNA the armour it needs

  • Sponge-like spheres give RNA the armour it needs – MIT researchers have now come up with a novel delivery vehicle in which RNA is packed into microspheres so dense that they withstand degradation until they reach their destinations. The new system, described Feb. 26 in the journal Nature Materials, knocks down expression of specific genes as effectively as existing delivery methods, but with a much smaller dose of particles.
