Nanoparticles in biofilm systems – assessment of their interactions by magnetic susceptibility balance and magnetic resonance imaging

To contribute to a better understanding of the interaction between engineered nanoparticles (ENP) and real biofilms, a new analytical approach was demonstrated within this dissertation using a magnetic susceptibility balance and magnetic resonance imaging for in-situ and non-invasive measurements. The focus was to examine the role of the water matrix, particle properties and exposure time on the ENP-biofilm-interactions and biosorption in biofilm systems with compact and fluffy structures.
