Influencing proteins : A protein multichromophore system (photosystem I) is exposed to gold nanoparticles (NPs) and silver island films. In the presence of these nanostructures an altered fluorescence response of the chromophores is observed (see scheme), indicating a change in the protein function. A model to understand these plasmonic effects is generally applicable to other multichromophore systems.
