Tools for bioanalytical applications include enzyme-linked immunosorbent assays (ELISA) and biosensor measurements. They enable heterogeneous assays for the detection of biomolecules in a wide range of applications, such as the detection of disease markers in blood or contaminants in food or environmental samples. The assays are mostly based on the lock-and-key principle, where one of the binding partners is immobilized on the device surface. Surface functionalization techniques to prepare the devices for the analytical applications must take into account the physical and chemical stability of the materials involved. While ELISAs are usually performed in microplates made of polymers, the materials used in biosensor setups are more diverse; and the use of polymers may be limited to the encapsulation of the actual biosensor unit. The focus of this work is to develop and characterize chemical biofunctionalization methods, that are compatible with typical polymers used in bioanalytical applications.
