Abstract

A new citrate-reduced silver hydrosol coated with ω-mercaptoalkanoic acids (mercaptopropionic and mercaptoundecanoic acids) self-assembled monolayers was prepared and characterized with surface-enhanced Raman spectroscopy. The structure and the quality of the coating monolayers are discussed and compared to similar coated and uncoated silver hydrosols previously developed. As an application, the new hydrosol was used as a biocompatible and efficient metal substrate for a surface-enhanced resonance Raman scattering (SERES) study of cytochrome c. The high-quality SERRS spectra reported of cytochrome c (obtained using only 1 μL of a micromolar cytochrome solution) are discussed and compared with data available from literature studies.
