Abstract
DNA origami nanorobots allow for the rational design of nanomachines that respond to environmental stimuli with preprogrammed tasks. To date, this mostly is achieved by constructing two-state switches that, upon activation, change their conformation, resulting in the performance of an operation. Their applicability is often limited to a single, specific stimulus-output combination because of their intrinsic properties as two-state systems only. This makes expanding them further challenging. Here, we addressed this limitation by introducing reconfigurable DNA origami arrays as networks of coupled two-state systems. This universal design strategy enables the integration of various operational units into any two-state system within the nanorobot, allowing it to process multiple stimuli, compute responses using multilevel Boolean logic, and execute a range of operations with controlled order, timing, and spatial position. We anticipate that this strategy will be instrumental in further developing DNA origami nanorobots for applications in various technological fields.
