Abstract

Porous silicon covered with metallic nanostructures has demonstrated significant potential over the last 15 years for surface-enhanced Raman spectroscopy (SERS), and the field is comprehensively reviewed. A range of porous silicon morphologies created via anodization, reactive ion etching, hydrothermal etching, and metal-assisted chemical etching (MACE) have been investigated. Porous silicon has been used as a tool to manage shape, dimensions, and spatial location of metallic nanostructures to meet the requirements for extremely sensitive and cost-effective SERS substrates. Detection limits for organic analytes as low as 10−16 M and enhancement factors up to 1010 have been reported with commercial products now starting to appear. Key attributes and challenges with porous silicon technology are discussed.
