We present a simple, generally applicable procedure for the assembly of nanoparticles oncarbon nanotubes in aqueous solution. The method makes use of polyelectrolytes for wrappingcarbon nanotubes and providing them with adsorption sites for electrostatically drivennanoparticle deposition. The method is exemplified by the assembly of gold nanoparticleswhich results in single, optically labelled carbon nanotubes.
