Raman spectroscopy is a powerful technique to detect and analyze the chemical compounds. However, the poor signal intensities from Raman scattering is the main issue for detecting the analytes at its low concentration. To overcome this problem, surface-enhanced Raman spectroscopy (SERS) had been proposed.Surface-enhanced Raman scattering has been intensely researched for many years as a great potential technique for ultra-trace detection. The enhanced Raman scattering of molecules adsorbed on rough metal surface. The metal surface serves as a highly sensitive detection tool. The mechanism based on the charge transfer between the molecule and adjacent surface. Therefore, the shape of metal will decide the effect of SERS. In this study, Ag nanoparticles with different size and morphologies were synthesized by simple methods from AgNO3, ascorbic acid in aqueous. The SERS effect was investigated using Ag flower-like with some analytes.
