Sample cleanup is a major processing step in many analytical assays. Here, we propose an approach to capture-and-release of analytes based on the DNA strand displacement reaction (SDR) and demonstrate its application to a fluoroimmunoassay on beads for a thyroid cancer biomarker, thyroglobulin. The SDR-based cleanup showed no interference from matrix molecules in serum.
