pH-Driven Dynamic Heterojunction Based on 2D ZIF-L@Ti-Fe-O Nanocages for Immobilization-Free Photoelectrochemical Sensing: Subpicomolar Monitoring of Typical Forever Chemical Perfluorooctanoic Acid.
The ultratrace determination of the typical "forever chemical" perfluorooctanoic acid (PFOA) is an urgent imperative due to its severe bioaccumulation and toxicity even at minute concentrations. However, its lack of redox and optical activity poses a significant challenge for conventional photoelectrochemical (PEC) sen...
