p> In this work we report the spectral evolution of the surfaceenhanced Raman scattering (SERS) response of biotin molecules that generate the assembly of Ag and Au nanospheres (NSs) into clusters with controlled interparticle gaps during the aggregation process. The experiments are analyzed using rigorous near-field electrodynamic calculations of th
