SERS sensor based on functionalized gold grating as a platform for the signal improvement on a portable Raman spectrometer
Original language description
We proposed a SERS-based universal sensor system, consisting of the highly-ordered gold grating, which enables to detect analytes on a molecular level and provide high reproducibility of response and a covalently grafted layer of organic functional groups (OFGs). OFGs serve as a capturing agent, enhancing the affinity to the analyte, what facilitates preconcentration of the analyte on the sensor surface and provide excellent selectivity. By proposed concept SERS sensor system can be functionalized by various ligands- for the rapid determination of metal ions, azo-dyes, cholesterol markers, DNA complementarity, trapping of pesticides and other contaminants, detection of specific markers of cancer cells, free radicals, enantiomeric excess in the validation of drugs. Suggested functionalized gold gratings demonstrate principal advantages for efficient SERS detection: expressivity, sensitivity, selectivity, pretreatment free procedure, and reproducibility.
