Evaluation of Surface-Enhanced Raman Scattering Substrate Consisting of Gold Nanoparticles Grown on Nanoarrays of Boehmite Fabricated using Magnetron Sputtering Process

A surface-enhanced Raman scattering (SERS) active structure allows the highly sensitive imaging of label-free molecular trace. gold nanostructure with boehmite as a skeleton was fabricated by inclined magnetron sputtering method. The characteristics prepared SERS plate consisting on were evaluated follows. distance dependence intensity 4,4′-bipyridine from edge substrate indicated that larger becomes closer approaches edged where nanolayer thicker. trend more pronounced at higher concentration molecule and less lower concentration. Using will enable further demonstration ultrasenstive detection chemical biological molecules environmental contaminants within broad range common fluidics for potential applications related to analytical chemistry monitoring.
