" titanium nanosheets arranged in an aqueous solution to create a wave that propagated through the material, even though the nanosheets were not attached to one another. They were also able to use the coordinated motion to transport microparticles along with the wave... living organisms can generate fine and intricate motions on demand, while engines can only repeat simple linear or circular motions"
