Dissipative assembly systems display cyclic autonomous assembly and disassembly with similar dynamics for repeated, consecutive injections of chemical fuel . Here we applied consecutive multimode potentials of 2.5 V, 400 Hz superimposed with a -400 mV steady potential and measured the average interparticle separation and fluorescein emission intensity near the cathode (See Supplementary Movie 12 for optical microscopy video). We used finite element analysis (FEA) implemented in COMSOL to solve the time dependent 1-D reaction-diffusion equations with the flux of charged species also driven by electromigration. The exchange current densities, redox potentials, diffusion coefficients, and pKa for each reaction were acquired from literature when possible and estimated if not available (See
