Benzoquinone, an electroactive molecule, has been utilized to electrochemically modulate pH in microfluidic devices and synthesize hydrogels . Rath et al. demonstrated that BQ redox can cause irreversible separation of colloids in an oscillatory electric field, but did not demonstrate transient responses . Here we present a hybrid approach to assemble transient colloidal crystals that combines aspects of electric field-directed and chemically fueled dissipative assembly.
