The nonequilibrium assembly in nature exists {at the|in the} microscopic and macroscopic scales, and represents {the most|probably the most|essentially the most|one of the most|by far the most} {common|typical|frequent|widespread|prevalent|popular} {way to|method to|approach to|strategy to|technique to|solution to} regulate object motions by consuming chemical fuels. In artificial nonequilibrium systems, {most of|the majority of} the {work|function|perform|operate} has focused {on the|around the} microscopic dissipative assembly, whereas the investigation on nonequilibrium assembly of macroscopic {building|developing|creating|constructing} blocks is {rarely|seldom|hardly ever} reported. {Here|Right here}, we present an {efficient|effective} {strategy|technique|method|approach|tactic} to dynamically mediate the interfacial chemistry of pH-responsive polyelectrolyte hydrogels, thereby regulating their macroscopic nonequilibrium assembly. The driving force for the assembly {is the|will be the|may be the|would be the|could be the|is definitely the} transient electrostatic attraction, {which is|that is|which can be} regulated by the biocatalytic feedback-driven temporal programming {of the|from the|in the|on the|with the|of your} pH {of the|from the|in the|on the|with the|of your} {system|method|program|technique}. The dissipative assembly {process|procedure|method|approach|course of action} {can be|may be|could be|might be|is often|is usually} controlled by adjusting the hydrogel parameters and fuel composition and {it can|it could|it may|it might} be repeated by refueling the {system|method|program|technique}. Most importantly, the ordered sewing of complementary hydrogels promotes the precise nonequilibrium supramolecular assembly to yield transient macroscopic supramolecular devices potentially {useful|helpful|beneficial|valuable} for timed release. 3-(2,5-Dichloropyrimidin-4-yl)-1H-indole Order Boc-NH-PEG8-CH2CH2NH2 site PMID:23551549
