Online Monitoring: Electrochemiluminescence based Gated Assay


To find new and better ways to detect and monitor contamination of water, food and the environment as early as possible directly at
the site of impact is one of the most pressing tasks for researchers today. Early detection of and strategic monitoring to trace
contamination of water is therefore crucial. This emphasizes the need for sensitive, robust, portable and affordable (especially for
low-income countries) analysis tools that can report directly at site on the concentration of a target contaminant. Detecting
contamination early means that these small, mobile analytical devices have to indicate analytes at very low concentrations with
reliable uncertainty and accuracy, to avoid false positives and foster acceptance of such tools by relevant user groups like public
employees. In this project, I will address this need relying on the integration of microfluidics, gated delivery systems, magnetic beads
and electrochemiluminescence (ECL) detection. ECL is a detection method that operates against a zero background and gated
delivery systems exhibit inherent features of signal amplification. A combination of both strategies with the versatile handling and
miniaturization capabilities of magnetic beads and microfluidics promises to yield user-friendly, affordable and robust analytical
devices with unprecedented performance for the reliable quantification of analytes at ultra-trace levels (ppb and below) directly onsite
at the point-of-need. By matching my expertise in electrochemistry and microfluidics with the host’s expertise in gated delivery
systems, magnetic beads, luminescence spectroscopy and device integration, I have the unique opportunity to receive training in
various other disciplines, including metrology, that allow me to broaden my field of knowledge and to better shape the outline of
my future career as a high-level (bio)analytical scientist.
