5.   Results – Kinetic Measurements

In this chapter, the principle of the time-resolved measurements is introduced. In contrast to the common principles of static measurements and static feature extractions, this approach allows the simultaneous quantification of a virtually unlimited number of analytes. Although some sporadic reports of time-resolved measurements in chemical sensing can be found in literature, no systematic investigations of time-resolved measurements, no systematic exploi­tations of the time domain and no transfers to different setups and measurement principles have been reported for chemical sensing up to now. Although the approach of the time-resolved measurements can be used for many different transduction and interaction principles, this study focuses on the application of one specific polymer for the time-resolved measure­ments. Thus, after an explanation of the static and the time-resolved sensor measurements this polymer is introduced. Then different properties of the polymer and different interactions of the polymer with analyte molecules are investigated as the understanding of these properties and interactions allows tweaking the sensors for different analytical tasks. This tuning is demonstrated in the last sections of this chapter.
