Electropositive Magnetic Fluorescent Nanoprobe‐Mediated Immunochromatographic Assay for the Ultrasensitive and Simultaneous Detection of Bacteria (Adv. Sci. 12/2025)

Immunochromatographic Assay for Bacteria Detection In article number 2412421, Chongwen Wang, Bing Gu, and co-workers report for the first time an ultrasensitive universal immunochromatographic platform for bacterial diagnosis, based on the broad-spectrum capture capability of electropositive MagMQD@Si+ probe towards negatively charged bacterial cells. This method is expected to become an efficient tool for the rapid and accurate detection of pathogens in clinical and POCT settings.
