Surface-Enhanced Characterization of Nanoparticle Surfaces — •Christian Kuttner1,2, Roland P.M. Höller1, Martin Mayer1,2, Max J.

We present the retrieval of molecular information at nanoparticle surfaces using surface-enhanced Raman scattering (SERS). The electric-field enhancement of the localized surface plasmon resonances (LSPRs) of noble metal nanoparticles can be exploited for the local characterization of their molecular surface near field. [1]

Consequently, we studied the nanoparticles’ ligand corona in dispersion and its exchange based on the example of low-molecular-weight surfactants against high-molecular-weight proteins. [2]
