摘要：
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. © 2010 Wiley-VCH Verlag GmbH & Co.
