Diseño de nano-estructuras plasmónicas para espectroscopia sers ultasensible: comparacion entre el autoensamblado y la bioconjugacion. (Desing of plasmomic nano-structures for sers... by Fraire, Juan C., Coronado, Eduardo A.

“…Homodimer aggregates with an interparticle gap of around 8 nm are generated in aqueous dispersions by the highly specific molecular recognition of biotinylated Au NSs to streptavidin (STV), while compact-tight Au NS aggregates with a gap of 5 nm are formed in the absence of STV due to hydrogen bonding among biotinylated NSs. …”
