Abstract

Biological processes rely on transient non-covalent interactions that govern the assembly of molecular building blocks into higher order, multi-component systems with emergent functions and topologies. A platform for the dynamic assembly of synthetic multicomponent complexes, analogous to the above, would provide novel entries to study and modulate the assembly of synthetic systems into higher order topologies. Here, we establish a hybrid DNA origami-based approach as an assembly platform that enables dynamic templating of supramolecular architectures. It entails the site-selective recruitment of multicomponent supramolecular polymers to the DNA origami platform with preservation of the intrinsic dynamics and reversibility of the assembly process. We show that the composition of the supramolecular assembly on the platform can be tuned dynamically and that the system allows for monomer rearrangement as well as for the inclusion of molecular cargo. We envision that this work lays the conceptual basis for studying synthetic supramolecular structures in their native environment in real-time and provides the basis new strategies for controlled multicomponent self-assembly of synthetic building blocks.
