A stimulus-responsive biohybrid material is described that rapidly dissolves at pathological concentrations of the gouty arthritis-causing metabolite urate. The gel consists of polyacrylamide and DNA that are crosslinked by the Deinococcus radiodurans-derived urate sensor HucR, which binds its specific target DNA motif at physiological urate concentrations and dissociates thereof at pathological concentrations.
