Assembly and optically triggered disassembly of lipid-DNA origami fibers
CHEMICAL COMMUNICATIONS(2023)
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. DNA origami and a photosensitive lipid are co-assembled into ordered fibers, which can be disassembled through UV-A light exposure.
