Abstract

Dispersion stability, ligand structure and conformation, and SERS activities of 1-alkanethiol (C n H 2 n +1 SH, n = 2–14) functionalized gold and silver nanoparticles (AuNPs and AgNPs) were studied as a function of alkanethiol carbon chain length and nanoparticle (NP) type and size. The dispersion s...
