Abstract: (1914 Views)
In this study, silver nanoparticles were synthesized using a chemical method with a reducing agent of sucrose at a temperature of 50°C. Subsequently, the silver nanoparticles were deposited on glass substrates using drop-coating to build active SERS substrates. Different analyses including UV-Vis spectroscopy (UV-Vis), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and energy-dispersive X-ray spectroscopy (EDS) were obtained to investigate the characterizations of silver nanoparticles. Since silvery substrates could enhance the Raman signal of molecules, these silvery substrates were used to investigate the molecular and biological detection. The active SERS substrates were obtained to detect 10-2 M of gelatine. In this paper, by carving gelatine in 10-2 M on silvery substrates by a physical method. The silver nanoparticles plasmonic resonance cause of an increase of SERS intensity. In compare with FT-IR spectrum, SERS substrates is an easy way to obtain gelatine.
