Monolayers of Amino Acid-Synthesized Gold Nanoparticles as SERS Substrates for Trace Chemical Sensing.

ABSTRACT: In recent years, extensive studies have been devoted to the applications of surface-enhanced Raman spectroscopy (SERS) in detecting and identifying trace amounts of various analytes. The crucial issue for SERS applications is the selection of reliable and reproducible substrates. Therefore, most studies were dedicated to their fabrication, characterization, and evaluation using selected test compounds. This article reports the results of comparative studies on the fabrication, characterization, and evaluation of SERS substrates in the form of monolayers of amino acid-synthesized gold nanoparticles (AuNPs) on silicon and glass platforms. The combination of AuNPs synthesized with five amino acids and four platforms with smooth and rough surfaces yielded 17 potential SERS substrates. SERS sub
