Surface Enhanced Raman Spectroscopy is a powerful analytical tool to obtain information on molecular composition. This technique has advanced greatly since its discovery, allowing Raman spectroscopic analysis down to the detection of single molecule. The heart of SERS performance lies on the choice and fabrication of SERS substrate. The most investigated metals for SERS substrates are Au and Ag. Unfortunately, the fabrication of such devises poses a significant challenge due to an expensive deposition technology including, vapor deposition, electron-beam lithography, focused ion-beam lithography, and nano-transfer printing. Herein, we report a simple and low-cost solution processing method to fabricate SERS substrates. Au nanoparticles and Au/CdS core/shell nanoparticles were synthesized and their solutions deposited on glass plates in the form of nanoparticle films. Although the enhancement of Raman signal due to Ag nanoparticle substrates is greater than that of Au, the high stability and a wide variety of fabrication methods makes Au nanoparticles more favorable candidates for SERS substrates. The performance of the SERS substrates fabricated using this method was found to be comparable with the commercially available substrates.
