A label-free, resettable, and colorimetric logic network has been realized by utilizing thermally regenerable cerium oxide nanoparticles and biocatalytic reactions. Coupling switchable CeO2 nanoparticles with biocomputing would convert molecular recognition events into colorimetric outputs and make logic gates feasible to reset.
