We have used CVD grown carbon nanotubes to electrically contact an individual 7 nm gold particle by scanning probe manipulation. The result was a single-electron transistor showing a periodic modulation of the current as a function of gate voltage for temperatures up to ~ 200 K. Based on a theoretical fit we conclude that the particle was responsible for the main features of the electron transport, whereas charging effects in the nanotube leads only appeared as a fine-structure. This interpretation could later be verified when the gold particle was removed and the two nanotubes were moved into electrical contact.
