Abstract
A novel lateral flow biosensor for rapid detection of Pb2+ was established for the first time based on Pb2+-induced G-quadruplex structure-switching. Semi-quantitative results could be read by reference to a colorimetric card. The whole process only took 15 minutes with a visual detection limit of 25 nM.
