Interparticle coupling, eg by various ligands, DNA strands, results in bathochro-mic shifts of the plasmon bands. Interaction of two (or more) nanoparticles results in collective resonance within the whole assembly, so the effective size of the particle is increased [13,19,20],... 

Figure 3.11. Electrodeposition of (a) silver nanoparticles and (b) silver nanowires. The co-evolution of hydrogen gas during electrodeposition is thought to assist in monodisperse nanocluster growth by interrupting interparticle coupling via convection effects at the electrode surface and surface mobilization of growing nanoclusters.
