Contamination of drinking water with pharmaceuticals is an emerging problem and a potential health threat. Immunochemical methods based on the binding of the analyte to specific antibodies enable fast and cost-effective on-site analyses. Magnetic bead-based immunoassays allow for implementation into an immunosensor for online testing. These particles are prepared by either coupling the analyte molecule (diclofenac) or the respective antibody (amoxicillin) to the surface. For miniaturization, detection is performed electrochemically on a microfluidic chip. The developed immunosensor will enable detection of pharmaceuticals directly in water supply pipes.

For miniaturization, detection is performed electrochemically (chronoamperometry) on a microfluidic chip.
