Au-Interaction of Slp1 polymers and monolayer from Lysinibacillus sphaericus JG-B53 - QCM-D, ICP-MS and AFM as tools for biomolecule-metal studies

Au-Interaction of Slp1 polymers and monolayer from Lysinibacillus sphaericus JG-B53 - QCM-D, ICP-MS and AFM as tools for biomolecule-metal studies

Suhr, M.; Raff, J.; Pollmann, K.

To obtain basic information on the sorption and recycling of gold from aqueous systems the interaction of Au(III) and Au(0) nanoparticles on S-layer proteins were investigated. The sorption of protein polymers was investigated by ICP-MS and that of proteinaceous monolayers by QCM-D. Subsequent AFM enable the imaging of the nanostructures.
