Diazonium-modification of plasmonic surfaces designed by laser ablation
Original language description
In this chapter, the utilization of diazonium chemistry for surface modification of plasmon-active surface(s) and the creation of analyte-targeted SERS substrates is discussed. Such substrates are able to selectively entrap and recognize the targeted analyte from solution by SERS measurement, ensuring its detection at very low concentrations even at dominant background of interfering molecules. The stability of diazonium-created coatings allows performing several steps of plasmonic surface modification and their subsequent utilization in various, often challenging conditions. In the first part of the chapter, the main principle of SERS method and functional SERS substrates is described. In the second part, the preparation and diazonium-functionalization of plasmon-active grating surface aimed at selective SERS detection are discussed. In the last part of the chapter, several examples of diazonium chemistry utilization for SERS-based recognition of enantiomers, environmental contaminants, dangerous compounds, and disease markers are given.
