- Abstract
- DNA-tethered lipid bilayers have been used in many studies, based on the controllable and well-defined properties of DNA tethers. However, their application has been limited, because it is difficult to cover a wide range of surfaces and achieve electrical insulation. We implemented an existing method, where a DNA hybrid chip on a silica or glass surface supports a lipid membrane using solvent-assisted self-assembly. The formation of a continuous lipid bilayer was confirmed through the change in quartz crystal microbalance dissipation results, depending on the presence or absence of DNA hybrids. The fluidity of the DNA-tethered lipid membranes was analyzed using a fluorescence microscope. The electrochemical analysis demonstrated the versatility of this new technique, which can be used for sensor or electrode surface modification for biosensors or bioelectronics. © 2023 American Chemical Society.
