Abstract
A surface enhanced Raman spectroscopy (SERS) analytical device includes a substrate having a porous structure, and a plurality of plasmonic nanoparticles embedding in the porous structure and forming a sensing region. A method of detecting a target analyte in a sample includes contacting the sample with the substrate, whereby the target analyte, if present in the sample, is concentrated in the sensing matrix. The substrate may then be analyzed using SERS detection equipment.
