Spectroscopic and hydrodynamic characterisation of DNA‐linked gold nanoparticle dimers in solution using two‐photon photoluminescence by Midelet, J, El-Sagheer, A, Brown, T, Kanaras, A, Débarre, A, Werts, M

“…Moreover, as a result of the lack of plasmonic coupling in the dimers, the optical extinction, scattering and photoluminescence spectra of the DNA–AuNP complexes are not sufficiently different to distinguish between monomers and dimers. …”
