Layer-by-layer assembly of polyelectrolyte and gold nanoparticle for highly reproducible and stable SERS substrate

•SERS substrates were constructed by layer-by-layer assembly of PDDA and gold nanoparticles.•The SERS performances of the multilayer thin films could be tuned by simple adjusting different dipping cycles.•The SERS signals were highly reproducible and stable. Building high-quality surface-enhanced Ra...
