“…A detailed description of the mesoporous silicon fabrication and structure can be found in Reference [ 55 ]. Mesoporous silicon has mostly been used as a host for the creation of ordered nanostructures of other materials [ 56 , 57 ]. This is caused by the highly ordered skeletons of the mesoporous silicon itself which defines the shape and sizes of the structures of the guest materials introduced into/onto the porous layer.…”

The present work gives an overview of the developments in surface-enhanced Raman scattering (SERS) with metal-coated porous silicon used as an active substrate. We focused this review on the research referenced to SERS-active materials based on porous silicon, beginning from the patent application in 2002 and enclosing the studies of this year. Porous silicon and metal deposition technologies are discussed. Since the earliest studies, a number of fundamentally different plasmonic nanostructures including metallic dendrites, quasi-ordered arrays of metallic nanoparticles (NPs), and metallic nanovoids have been grown on porous silicon, defined by the morphology of this host material. SERS-active substrates based on porous silicon have been found to combine a high and well-reproducible signal level, storage stability, cost-effective technology and handy use. They make it possible to identify and study many compounds including biomolecules with a detection limit varying from milli- to femtomolar concentrations. The progress reviewed here demonstrates the great prospects for the extensive use of the metal-coated porous silicon for bioanalysis by SERS-spectroscopy.

“…The open structure of PS has driven scientists to introduce various "foreign" substances (such as metals and semiconductors) into its pores, in pursuit of creating nanocomposites and hybrid materials with electrophysical properties not akin to monocrystalline silicon [1]. In cases such as these PS plays the role of a "host" material, with the pore-filling material serving as a "guest".…”

A variety of micro‐ and nanocomposite materials based on electrochemically‐acquired porous silicon are produced and evaluated in terms of their applicability to display technology. It is shown that porous silicon provides a versatile and well‐adjustable template for filling with other materials, which can outright change its electrophysical parameters. While, in terms of display applications, porous silicon layers are mostly prominent for their photohiminescence not akin to monocrystalline silicon, this property can be additionally enhanced by employing a variety of electrochemical techniques to form metal deposits of certain shapes.
