Abstract
AbstractA major goal of nanotechnology and bioengineering is to build artificial nanomachines capable of generating specific membrane curvatures on demand. Inspired by natural membrane‐deforming proteins, we designed DNA‐origami curls that polymerize into nanosprings and show their efficacy in vesicle deformation. DNA‐coated membrane tubules emerge from spherical vesicles when DNA‐origami polymerization or high membrane‐surface coverage occurs. Unlike many previous methods, the DNA self‐assembly‐mediated membrane tubulation eliminates the need for detergents or top‐down manipulation. The DNA‐origami design and deformation conditions have substantial influence on the tubulation efficiency and tube morphology, underscoring the intricate interplay between lipid bilayers and vesicle‐deforming DNA structures.
