Sustained, Reversible, and Adaptive Non‐Equilibrium Steady States of a Dissipative DNA‐Based System
Angewandte Chemie, EarlyView.Continuous supply of an RNA chemical fuel allows sustained non‐equilibrium steady states (NESS) of a dissipative DNA strand‐displacement reaction to be achieved. The system can dynamically adapt in real‐time to subtle on‐the‐fly variations of fuel supply, demonstrating remarkable control over a dissipative process, which is unachievable when using ...

Control of Tetrazine Bioorthogonal Reactivity by Rotaxanation
Angewandte Chemie, EarlyView.Control of tetrazine‐mediated inverse electron demand Diels–Alder (IEDDA) reaction has been achieved by rotaxanation. Tetrazine rotaxanes were synthesized in high yield and they displayed a much slower kinetics compared to the corresponding thread. Mechanical bond disassembly upon the right stimulus activates reactivity.
