The aim of this study was to develop an ultra-concentration plant, which allows quantitative detection of viruses in 30,000-L-water samples. The developed enrichment system consists of a three-stage process. Two cross-flow ultrafiltration enrichment steps, as well as a monolithic affinity filtration allow to enrich 30,000 L of drinking water within 20 h to a final volume of 1 mL. This eluate can be directly used in quantitative detection methods such as PCR, microarray or plaque assay. Furthermore, the feasibility of visualization of contaminants in porous media using antibody-coupled paramagnetic nanoparticles (NP) and magnetic resonance imaging (MRI) was examined. For this, multi-functional Fe3O4-NP were prepared and characterized in detail. With this, a column filled with silica gel and a layer of B[a]P-coupled silica gel could be visualized by MRI.
