Surface‐enhanced fluorescence of in situ synthesized polysilanesilver nanoparticles

Abstract: To produce surface plasmons, silver nanoparticles are synthesized in situ in a pseudo‐template system based on polyhydrosilanes. Adsorption on the silver nanoparticle surface produces a thin layer of polymer with properties different from those of bulk polysilane. The metal‐adsorbed polymer layer serves as a spacer between the polysilane fluorophore and the plasmonic nanoparticle. This prevents quenching of the polysilane emission and leads to a strong surface‐enhanced fluorescence through coupling of surface … Show more

“…It should be noted that the interaction of AgNPs with light is the strongest among all known particles; therefore, small changes in the size of the NP, the dielectric function of the metal sphere or the polarity of the solvent have a strong impact on the observed absorption. [31][32][33] In the case of S-Chi, these effects can be demonstrated by comparing S-Chi stabilized AgNPs to a similar recently described system where heparin, another sulfated polysaccharide, was used as a stabilizer (size of the AgNPs ca. 10-28 nm).…”
