Metallic nanoparticles can exhibit very large optical extinction in the visible spectrum due to localized surface plasmon resonance. Spherical plasmonic nanoparticles have been the subject of numerous studies in recent years due to the fact that the scattering response of spheres can be analytically evaluated using Mie theory. However a major disadvantage of metallic spherical nanoparticles is ...

the silver spr chip was modified by alkaline-silane condensation with aminopropyltriethoxysilane (aptes) in naoh aqueous solution at different times. silver sputtered slides coated with aptes were immersed in naoh solution, enabling us to produce silver surfaces homogeneously covered with aptes. the surface properties of grafted aptes on sputtered silver surface as a occasion of time were studi...

In this paper, a fast and sensitive localized surface plasmon resonance (LSPR) based biosensor was developed and the optimization of gold – antibody conjugates through investigation of different parameters were performed. Gold nanoparticles (AuNPs) with a size of ~20 nm were synthesized via chemical reduction of HAuCl4 with trisodium citrate as reducing and stabilizing agent. The impacts of pH ...
