(a) A design of photo-sensitive DNA nanodevice that make use of the properties of azobenzene towards different wavelengths of light. (b) Making use of the cis-trans properties of azobenzene under different wavelengths to close or disclose the active site of enzyme. (c) The shape of the azobenzene modified DNA tetrahedron can be altered in the presence of different wavelengths.
