Assembly and optically triggered disassembly of lipid–DNA origami fibers

Abstract

The co-assembly of lipids and other compounds has recently gained increasing interest. Here, we report the formation of stimuli-responsive lipid–DNA origami fibers through the electrostatic co-assembly of cationic lipids and 6-helix bundle (6HB) DNA origami. The photosensitive lipid degrades when exposed to UV-A light, which allows a photoinduced, controlled release of the 6HBs from the fibers. The presented complexation strategy may find uses in developing responsive nanomaterials e.g. for therapeutics.
