Layered Assembly of Silver Nanocubes/Polyelectrolyte/Gold Film as an Efficient Substrate for Surface-Enhanced Raman Scattering

Abstract: Surface-enhanced Raman scattering (SERS) is of great importance for the sensitive, rapid, and repeatable detection of target analytes. The electromagnetic enhancement has a major contribution to the signal enhancement in SERS which is critically dependent on the micro-/nanomorphology of noble metal (e.g., Au and Ag) film substrates. Herein, Ag nanocubes/polyelectrolyte/Au (Ag/PE/Au) sandwich-structured film is fabricated by the layer-by-layer deposition and then utilized as an efficient SERS substrate by the c… Show more

“…Another effective solution for the production of sensitive SERS substrates is the use of multilayer structures that consist of several metals. A possible nanoplatform of this type is a Ag-NCs/polyelectrolyte/Au (Ag/PE/Au) sandwich-structured film, which is presented by Wang et al [ 111 ]. The fabrication of the Ag/PE/Au film involved layer-by-layer deposition.…”

“…[ 107 ] Metal nanocubes, the 3D nanostructures, have six flat faces (sides) together with 12 sharp edges and 8 sharp corners. [ 108 ] The enhanced local electromagnetic field can be concentrated or localized at their edges and especially at their sharp corners due to strong and tunable LSPR, hence a significant SERS enhancement factor of the molecules of interest attached to nanocubes can be realized. A better understanding of the nucleation and growth processes of the nanoscale particles has allowed the designs and development of even more diverse types of nanostructures with controlled tips, corners, and edges.…”
