Mater. 2022, 2209870 Hydrogel actuators are important for designing stimuli-sensitive soft robots. They generate mechanical motion by exploiting compartmentalized (de)swelling in response to a stimulus. However, classical switching methods, such as manually lowering or increasing the pH, cannot provide more complex autonomous motions. By coupling an autonom
Mo Sun, Jie Deng, Andreas Walther - Read the full article here: Angew. Chem. Int. Ed. 2022, e202214499 Two chemical-fuel-driven non-equilibrium DNA-based enzymatic reaction networks have been coupled with a RNA transcription system to achieve cross-regulation and feedback between each other. This approach gives different types of signal outputs, including repression, promotion, repression-recovery, and promotion-stop.
