“…S-layer platforms have been used for deposition and nucleation of FePt nanoparticles from the gas phase, 168 as well as for controlled placement of ferromagnetic nanoparticles from solution. 169 In addition to nanoparticles, metal nanorods and nanowires 170,171 have also been constructed using similar strategies, typically in combination with chemical vapor deposition.…”

“…As for SERS application, SiNW arrays are usually decorated with Ag or Au-NPs by using chemical methods [ 39 , 40 , 41 , 42 ]. The advantages of chemical deposition include its implementation and simplicity; self-induced deposition does not need vacuum technology or a power supply [ 41 ]. Ag-NPs usually exhibit better plasmonic enhancement of SERS, but they do not possess surface stability and biocompatibility in comparison with Au-NPs [ 42 ].…”

Silicon nanowires (SiNWs) prepared by metal-assisted chemical etching of crystalline silicon wafers followed by deposition of plasmonic gold (Au) nanoparticles (NPs) were explored as templates for surface-enhanced Raman scattering (SERS) from probe molecules of Methylene blue and Rhodamine B. The filling factor by pores (porosity) of SiNW arrays was found to control the SERS efficiency, and the maximal enhancement was observed for the samples with porosity of 55%, which corresponded to dense arrays of SiNWs. The obtained results are discussed in terms of the electromagnetic enhancement of SERS related to the localized surface plasmon resonances in Au-NPs on SiNW’s surfaces accompanied with light scattering in the SiNW arrays. The observed SERS effect combined with the high stability of Au-NPs, scalability, and relatively simple preparation method are promising for the application of SiNW:Au-NP hybrid nanostructures as templates in molecular sensorics.
