Preparing anisotropic nanoparticles is always a huge inspiration for people who research in this field. Unlike conventional spherical nanoparticles whose plasmon is spread equally on entire its surface due to its symmetric property, the anisotropic nano-structures which own tips on their surfaces will have abnormal electromagnetic properties. In this thesis, we carried out synthesizing silver nanoplates and gold nanoflowers without using any surfactants or hydrophilic polymers as traditional approaches often used. This aims to improve surface-enhanced Raman scattering (SERS) of these anisotropic structures. Silver nanoplates can be successfully synthesized using aromatic stabilizers such as phenylphosphonic acid and lactobionic acid. The colors of silver nanoplates could be tuned by controlling the amount of H2O2, On the other hand, nanoflowers could be prepared using ascorbic acid and citric acid for surface enhanced Raman scattering.
