In this thesis, the development of a new readout method for microarray detection of microorganisms is discussed. The detection is based on surface-enhanced Raman scattering (SERS) and enables the label-free detection of bacteria in water and aerosol matrices in situ. The advantages of the method are a label-free, fast and selective analysis of multiple bacteria. The characterization is feasible in water which prevents the analytes from dehydration and denaturising. For the analysis of the molecular composition of cell walls, this could be of advantage. Additionally, it presents the facility to analyze microarrays quantitatively with Raman. In this work, a completely new approach for the identification and quantification of bacteria is demonstrated.
