The electrical transport properties of double‐walled carbon nanotubes (DWNTs) change dramatically when different single‐stranded DNA (ssDNA) molecules are encapsulated, depending on the type of DNA base. Cytosine‐containing ssDNA@DWNTs exhibit p‐type transport behavior, in contrast to the n‐type characteristic of guanine‐containing ssDNA@DWNTs, due to the charge‐transfer effect between ssDNA and DWNTs.
