Abstract

We report the synthesis of silver–gold nanotubes containing hot spots along their surface. The Ag–Au nanotubes exhibited exceptional SERS properties compared to silver nanowires, enabling the detection of crystal violet in the 10−10 M regime, as well as 9-nitroanthracene and benzo[a]pyrene at 3.3 × 10−7 M.
