Silver colloids prepared by laser ablation in water have been linked using sp-hybridized carbon chains thus obtaining a plasmonic transfer between the metallic nanoparticles. It has been found that the state of the metallic surface is of fundamental importance for the plasmonic transfer. The role of the carbon π-electron system has been considered in order to justify the electromagnetic field amplification and the observed surface enhanced Raman signals. These findings open the possibility to control the electronic transfer between different metallic nanostructures for the application in future plasmonic devices.
