Single-walled carbon nanotubes (SWNTs) decorated with two types of single-stranded DNA (ssDNA), with 30 adenine or 15 adenine/15 guanine residues (AG30), exhibit ambipolar or n-type transport characteristics, respectively. The electron-transfer properties of the ssDNA/SWNTs are sensitive to light, and the response of field-effect transistors is reflected in a shift of the threshold voltage, thus demonstrating a photoswitching effect.
