Here, we present new approaches for the fabrication of stimuli-responsive dynamic nanostructures. Dual-responsive DNA diblock copolymers and triblock copolymers were synthesized by coupling a thermo-responsive polymer, poly(N-isopropylacrylamide (PNIPAM) and an oligonucleotide. Such DNA block copolymer micelles can undergo sphere-to-cylinder shape transformation in response to the temperature change and programmable DNA binding events, demonstrating the multi-dimensional dual responsive shape changing capability. Furthermore, we present a new approach to fabricate dynamic and responsive free standing films of nanoparticles, based on the programmable DNA-directed self-assembly and the layer-by-layer (LbL) thin film fabrication technique. We demonstrate that the new approach provides a powerful means to generate dynamic nanostructures that can undergo complex and programmable shape transformation.
