Dual‐Channel Interdigitated Aptamer‐Based Sensors for Rapid Small‐Molecule Detection in Biofluids

Angewandte Chemie International Edition, Volume 65, Issue 27, 1 July 2026.
An electrochemical aptamer sensing chip employs dual interdigitated electrodes and selective self‐assembled monolayer removal to convert small‐molecule recognition into robust “signal‐off/on” responses. This dual‐channel signal conversion minimizes background noise and accelerates probe diffusion, enabling rapid (as fast as 5–30 min), low‐volume ...
