Paper Abstract

Ultrathin porous silicon membranes provide a novel platform for label free detection and identification of biological samples using SERS. A 15 nm thin gold metal film was deposited on top of a 30 nm thick porous silicon membrane to form a thin porous metallic film. 3D FDTD simulations show EM field enhancement inside the holes together with increased scattering and extinction cross sections, making this structure a novel SERS substrate.
