A portable molecularly imprinted polymer-modified microchip sensor for the rapid detection of perfluorooctanoic acid

Cu 2 O@C@NiCo 2 O 4 was introduced to the MIP sensor to enhance the PFOA sensitivity, which achieved an LOD of 19.65 ng L −1 with a wide linear range of 207–4140 ng L −1 . This MIP sensor was also applied in a disposable microchip sensor for PFOA detection.
