A Fluorescent Conjugated Polymer-based Ratiometric Aptasensor for Highly Specific and Robust Detection of Perfluorooctanoic Acid

Chem. Commun., 2026, Accepted Manuscript DOI: 10.1039/D5CC07080E, Communication Hao Liu, Qinfeng Xu, Zhao-zhao Zhang, Yan-ni Li, Chun-Yang Zhang We develop a fluorescent conjugated polymer–based ratiometric aptasensor for highly specific and robust detection of perfluorooctanoic acid (PFOA). The presence of PFOA can induce the aptamer folding and consequently the...
