In this symposium, I will introduce our recent results how to construct dynamic self-assembled nanostructures exhibiting switchable functions, inspired by life systems. For example, synthetic tubular pores are able to undergo open-closed gating driven by an external signal, which function as an artificial enzyme. When self-assembled tubules embed DNA inside the hollow cavities, the DNA-coat assembly undergoes collective motion in helicity switching. In the case of toroid assembly, the static toroids are able to undergo spontaneous helical growth when they switch into out-of-equilibrium state. The helical growing drives actuation of spherical vesicles into tubular vesicles, reminiscent of microtubles. Moving from 1-D to 2-D structures, the internal pores are able to form chiral interior which selectively capture only one enantiomer in racemic solution with pumping action. I will discuss recently discovered these results with their complex functions.
