Abstract: The DNA origami technique has emerged as one of the most versatile bottom-up nanofabrication methods. In this talk I will discuss our recent results related to application of DNA origami for fabrication of plasmonic systems with novel stimuli and optical responses. Specifically, we will present fabrication of i) light-responsive dynamic plasmonic assemblies with easily regulated steady out-of-equilibrium states1; ii) chiral plasmonic systems with visually detectable reconfigurable optical activity; iii) metal shells with tailored complex morphologies and optical responses within near-infrared transparency window(s).
