Abstract

Silver nanowires functionalized with gold nanoparticles using a polyacrylic acid linker exhibit pH-modulated optical properties, including a shift in localized surface plasmon resonance, and triggered surface-enhanced Raman scattering (SERS) effects. The tunable optical properties are exhibited as a result of changes in particle coupling caused by the swelling response of polyacrylic acid.
