Gold Nanorod Arrays Surface Enhanced Raman Scattering (SERS) substrate is designed for Raman signal enhancement and highly reproducible & ultrasensitive measurements.    SERS is a powerful technique for the detection, identification, quantification and structural studies of minute amounts of samples in materials research, surface science, medical diagnostics, biophysics etc.

Au Nanorod Arrays SERS Plate has created a SERS plate coated with a gold nanorod array by performing two-way oblique deposition on SiO2 and oblique deposition of gold by "dynamic oblique deposition". This process achieves high reproducibility without using expensive processes such as etching and lithography. The fabricated surface has a long-dimensional nanoparticle structure with strong anisotropy, and the Raman scattering of adsorbed particles is enhanced by the effect of plasma resonance using Au-oblate nanoparticles as a field. In addition, the surface is strong, and it is possible to measure in the solution state by placing a cover glass to prevent evaporation in addition to drying the sample after dropping.
