Refractive index sensitivity of Au nanostructures in solution and on the substrate

Abstract In this work, we present the synthesis and surface immobilization of Au nanostars, nanocubes nanorods for localized plasmon resonance (LSPR)-based refractometric sensing applications. nanostructures exhibiting LSPR peak positions in 500–900 nm spectral range were prepared by seed-mediated method. The refractive index (RI) sensitivity all these colloidal solution measured sample highest each category immobilized on glass substrate. investigated RI sensing. nanostars having position at 767 exhibited 484 nm/RIU 318 This study gives an outline selecting developing plasmonic platforms.
