Traditionally, chemical oscillations were achieved using organic and inorganic reagents in continuous stirred tank reactors and flows or enzymatic networks. The key design components include an interplay between positive and negative feedback loops separated by a time delay. Although the above-mentioned oscillating responses have been exploited to induce similar patterns in colloids, polymers, or gels, the macroscopic manifestation of oscillatory patterns -detectable by the naked eye -seems to be reserved only for molecular systems. The central hypothesis of the present work states that hierarchical design of nanoparticlesbased systems in which thermoresponsive surface ligands regulate the reversible clustering of nanoparticles under uninterrupted light conditions can eventually generate oscillatory signatures driven by hydrodynamic convection (Figure ). that in turn set the initial conditions for oscillatory convection upon disassembly on macro scale. b) Feedback mechanism. Under non-periodic light conditions at NIR, the binary mixture of gold spheres and rods show minimal light-harvesting capabilities and undergoes spontaneous assembly through DNA hybridization (positive feedback). Upon successful assembly, the system eventually harvests enough light energy at NIR to initiate photothermal disassembly (negative feedback). The oscillatory features emerge from light-induced asymmetry (shown in c), wherein preferential interaction of assemblies with light accelerates their own disassembly.
