Deposition of individual single-wall carbon nanotubes over multiple (up to seven) Pt nanoelectrodes is realized. Two-probe and four-probe transport measurements between adjacent pairs of electrodes show similar but not identical single-electron Coulomb charging signatures at low temperatures. The observations indicate that nanotubes can behave as a chain of quantum wires connected in series. We argue that the local harriers separating these islands may be caused by bending of the tube near the edges of electrodes.
