Abstract
A surface enhanced Raman spectroscopy (SERS) device, comprises a non-electrically conductive substrate, at least two microelectrodes disposed on the substrate in a spaced relationship such that a detection site is formed along edges and/or between opposing edges of the microelectrodes, and a nanoparticle structure comprising a plurality of metallic nanoparticles disposed in the detection site. Assembly of the nanoparticle structure may be directed by an electric field between the at least two microelectrodes. The SERS device is inexpensive, robust, portable, and reusable. Also described herein are methods for using and preparing the SERS devices with simple, rapid, and inexpensive fabrication techniques.
