Simulation of LSPR optical and electric field enhancement distribution based on gold nanobipyramids using a modified nanosphere

Polyacrylonitrile as a versatile matrix for gold nanoparticle-based SERS substrates

“…[1][2][3][4] The method is primarily based on the localised surface plasmon resonance (LSPR) phenomenon. 5,6 LSPR occurs when molecules are in close proximity to nanostructures made of noble metals, which causes the Raman signal to be amplied. 7,8 SERS uses the electromagnetic and chemical phenomena that occur when analyte molecules are near nanostructures to amplify Raman signals.…”
